User talk:J heisenberg

From Wikipedia, the free encyclopedia

Sorry to be a nuisance but I wonder if you could explain the comment "the log of the data will be stationary instead of the original". Surely if a data set is not stationary then neither is its log? --Richard Clegg 13:03, 16 Feb 2005 (UTC)

Many data series are not stationary (stock prices), but when "logged" and de-trended they are (maybe only close to stationary). --J heisenberg 18:34, 16 Feb 2005 (UTC)

Surely then it is the detrending that makes them stationary? Unless I am totally misunderstanding, if X_t is a stationary time series then log(X_t) [if it exists] is surely also stationary? And if log(X_t) is stationary then X_t is surely also stationary. I may be wrong in this and would like to know more. Could you perhaps provide a reference to an explation for me? --Richard Clegg 19:22, 16 Feb 2005 (UTC)

As I understood it, a stationary process is one who's distribution is constant over time (identically distributed). Stock prices will not be that, since its variance will be greater at Dow 10000 than at Dow 1000. However, log(Dow) could be stationary, if variance is proportionally the same at 10000 and 1000. Maybe I just misunderstood "stationary"? Regards, --J heisenberg 19:39, 16 Feb 2005 (UTC)

Remember that stationarity requires that the mean as well as the variance is constant. It is commonly the case that the increments of the logs of stock prices are considered stationary. Perhaps that is what you mean? A non-stationary process often has stationary increments and it is no surprise to find the increments of the log of a non-stationary process to be stationary. --Richard Clegg 16:54, 17 Feb 2005 (UTC)

Right. If the process is "exponential" in nature, like economic growth is (at least not looked at from a green perspective), the logged process will be (trend-)stationary. And if Wall Street is a random walk, then its (logged) diffs will be stationary ;) --J heisenberg 17:33, 17 Feb 2005 (UTC)

Sounds reasonable though with the caveat that I lecture in maths/stats and am ignorant of economics. --Richard Clegg 18:18, 17 Feb 2005 (UTC)

If you think the comments are too "pedestrian" there, remove them. I basically wanted a link for "trend stationary"--J heisenberg 19:43, 16 Feb 2005 (UTC)

No problem -- I have fixed it up slightly. Hope it is nothing which offends you. I've left you a link for trend-stationary. --Richard Clegg 19:59, 16 Feb 2005 (UTC

[edit] Templates added to Oral sex and Zoophilia, removed by Tony Sidaway

I removed the templates because they are misleading. See the site content disclaimer. Wikipedia as a whole is emphatically not child-safe. --Tony Sidaway|Talk 12:03, 20 Feb 2005 (UTC)

Whether Monetary policy is child-safe is neither here nor there. Wikipedia as a whole is not. It would be wrong to state that any part of Wikipedia can be browsed by an unattended child. Links within Wikipedia can take the child to sections that are not "child safe". --Tony Sidaway|Talk 12:13, 20 Feb 2005 (UTC)

Sorry for using a colloquialism, "neither here nor there." It means "not really relevant." I mean that you can list any number of child-safe articles, but if some articles are not then the whole site is not child-safe. --Tony Sidaway|Talk 15:44, 21 Feb 2005 (UTC)

Please reconsider what you are doing; whilst I understand and sympathise with your motives, you are going against the consensus developed on the mailing list that the information needed for downstream content selection should be possible to obtain from category information, not templates. For example, the category "Sexology" might be a clue here that some people might not want their children to have access to this article. Similarly, images can be assigned to categories relating to explicit sexual or violent content, allowing downstream filtering policies to be implemented in terms of these labels. This also solves the image inlining/linking problem. In this way, adults can see a fully uncensored Wikipedia without extraneous templates, whilst still allowing appropriately filtered content to be generated for children as soon as we have the filtering software ready. -- The Anome 12:21, Feb 20, 2005 (UTC)

[edit] Hafiz

Apologies for butting in. The term "hafiz" is an Arabic word from the root for "protection". A common use, for example, is as the shortened term for someone who has memorized the whole Qur'an, a Hafiz-ul-Qur'an.—iFaqeer (Talk to me!) 20:00, Mar 24, 2005 (UTC)

[edit] Reason for copyvio notice on London Convention?

I only just now noticed the copyvio notice you posted on the London Convention page, and I've reverted it temporarily to prevent its pending deletion while I try to find out why it was listed as such. Both of the sources I used are public domain as far as I was able to determine, and you provided no explanation in the edit summary or talk: page for why you thought otherwise. Could you explain on Talk:London Convention? Bryan 07:17, 29 Mar 2005 (UTC)

[edit] List of cities over 100,000

The reason I removed "Sudbury" from the Canadian list is that the city's name is Greater Sudbury; there's no "City of Sudbury" in Canada that exists separately from the "City of Greater Sudbury". Also, Brantford and Peterborough don't belong on the list as they aren't over 100,000, Cape Breton and Saanich aren't cities, and Kelowna and Moncton are only over 100,000 if you include the surrounding areas outside of the cities themselves. Bearcat 00:35, 28 Apr 2005 (UTC)

[edit] Missing encylopedia topics.

Hi, i noticed you have a list of Nuttall topics missing from Wiki, i have just created WikiProject Missing encyclopedic articles, do you think it would be appropriate to include your list in this project? if so please add relavent links to the project page. thanks Bluemoose 10:34, 11 Jun 2005 (UTC)

[edit] quasilinear

Hi, you created the redirect Quasilinear => Utility, but there is no information about what it means on that page. I know "quasilinear" in the context of growth classes, for functions that grow like n·log(n) (or more generally functions that are O(n^a) for any a>1).

I considered adding this terminology in Big O notation, and also making a redirect to there. If the utility function you refer to is related to this idea of growth, maybe you agree, else we should make a disabiguation page for the 2 different meanings. But currently is is a bit frustrating to come to the "utility" page with no information about what "quasilinear" means. Thanks in advance for your answer and opions. — MFH: Talk 22:04, 21 Jun 2005 (UTC)

[edit] 1911xNuttall

I would like to do the other combinations, but I just left for vacation today, and of course the "cross-reading" script is on the machine I didn't bring :-( So you'll have to be patient for two weeks, until I get back. In the meantime, you'll have to do with 1911x2004 and 2004xEncarta. If you like lists, you could look at Chemicals, People, and Stuff ;-) Or you could start a new encyclopedia list, for an encyclopedia about Austria (no PD articles, though). --Magnus Manske 19:45, August 9, 2005 (UTC)

[edit] Amphictyonic Council

That was silly of me! The merge for Amphictyonic Council now points to Amphictyonic League. Thanks for warning me about that. Dejvid 15:26, 9 September 2005 (UTC)

[edit] Count of Capo d'Istria

I couldna never done that. But then I pull from the æther stuff you fill out, as do I, as with Henry Tracey Coxwell. Some of the redirects are moronic misspellings, but such is wikipedia. And I even know what the Amphictyonic Council was; Herc the Jerk, the porter, got promoted after what's-her-name abdicated. --FourthAve 06:09, 10 September 2005 (UTC)

[edit] Year links

See Wikipedia:Manual of Style (dates and numbers)#Date formatting. In general, there is reason to link full dates (day month and year) because that activates date preferences. There is no good reason to link years alone, as a rule -- it just clutters up the article, adn makes year article vastly over-linked-to. I routinely remove year-only links when I encounter them. DES ^(talk) 22:14, 13 September 2005 (UTC)

Notice that this link is regarding date preferences, the ability of wikipedia to bring February 7 and 7 February to the same page, and is not a style indicator. DES is confused about this, the link you posted on his talk page is an actual Manual entry on this topic and clearly shows Socrates having linked years. Usrnme h8er 15:48, 15 September 2005 (UTC)

[edit] Pruning lists

The crossover lists based on at least one of the removed lists will not be updated; the others might be once I get around to it (next week;-) --Magnus Manske 16:31, 16 September 2005 (UTC)

Yes, manual updating - or we remove them altogether and focus on the Hotlist stuff instead... --Magnus Manske 16:45, 16 September 2005 (UTC)

[edit] Southern Alps

Hi - I've just reverted your categorisation on Southern Alps. Putting a New Zealand mountain range in Cat:Mountain ranges of Australia is about as likely to cause offence as if I categorised Munich in Cat:Cities in France! Grutness...wha? 14:00, 20 September 2005 (UTC)

Well, Australia's part of oceania too... perhas Cat:Mountain ranges of Australia and Cat:Mountain ranges of New Zealand should both be subcategories of Cat:Mountain ranges of Oceania (I think I'll do that now, in fact). Grutness...wha? 14:20, 20 September 2005 (UTC)

[edit] Image:161px-Chevert-coin.jpg

[edit] Alice Fletcher image "Fieldwork"

Hi I have tagged your image Image:Alice Fletcher 3.jpeg as probable PD please can you give me source that it came from, if possible try to get a larger image as the image is really too small and may be deleted. Thanks Arnie587 02:32, 2 October 2005 (UTC)

don't worry I have located better versions of these images and added them to the Alice Fletcher page Thanks Arnie587 02:49, 2 October 2005 (UTC)

Good additions. Were we both working on this at the same time? I think that is more likely to happen as the number of available Nuttall articles dwindles! David Brooks 14:48, 4 October 2005 (UTC)

[edit] Change to Stationary process

Hi! On Jan 12 2006 an anonymous contributor made a small change to the Stationary process page - changing a "+" to a "-" in a formula. I reverted the change because (1) the changer was anonymous; (2) he gave no reason for the change; (3) I find it easier to trust several original page editors rather than a lone later change; (4) a quick googling found another web page that supported the original version.

Since you actually seem to understand what the page is about, completely unlike me :-) could you check if I did a silly thing by reverting the change? Thanks!! Weregerbil 17:55, 12 January 2006 (UTC)

A tag has been placed on Accorso, requesting that it be speedily deleted from Wikipedia. This has been done because the article seems to be about a person, group of people, band, club, company, or web content, but it does not indicate how or why the subject is notable. If you can indicate why Accorso is really notable, you can contest the tagging. To do this, please affix the template {{hangon}} to the page and leave a note on Talk:Accorso, explaining how Accorso is notable. Please do not remove the speedy deletion tag yourself.

[edit] heads up nominated Joe_Bagstock for deletion

I've added the deletion template to the article Joe_Bagstock, suggesting that it be deleted according to the proposed deletion process. All contributions are appreciated, but I don't believe it satisfies Wikipedia's criteria for inclusion, and I've explained why in the deletion notice (see also Wikipedia:What Wikipedia is not and Wikipedia:Notability). Please either work to improve the article if the topic is worthy of inclusion in Wikipedia, or, if you disagree, discuss the issues raised at [[Talk:{{{1}}}]]. If you remove the deletion template, the article will not be deleted, but note that it may still be sent to Wikipedia:Articles for deletion, where it may be deleted if consensus to delete is reached.
