[edit] Notational and usage conventions

Hello. Your recent edits to log-normal distribution prompt two tips.

(1) Notice the difference between these:
(\frac{a}{b})


\left(\frac{a}{b}\right)
Allowing the parentheses to have the right size, as in the second case, is customary.
(2) "Partial expectation", with a lower-case initial "e", is correct Wikipedia style; capitalizing the "e" is not.

[edit] Invitation

Hi! You may be interested in following the discussions on the talk pages of Wikipedia:WikiProject Physics and Wikipedia:WikiProject Mathematics. If so, please think of putting yourself on the participants list for the projects as well. linas 03:52, 20 March 2006 (UTC)

[edit] People in systems and control

Hi, just wanted to compliment you on improving the People in systems and control article. Good job. Now the article makes more sense then when I first encountered it. Garion96 (talk) 01:42, 29 July 2006 (UTC)

Thank you! Encyclops 03:36, 29 July 2006 (UTC)

[edit] apologies

Hi. It seems I jumped the gun by tagging your article with the context template. I only realized later your "more to come" edit sumary. Feel free to remove it (although I still believe that it could have a bit more context!) Pascal.Tesson 19:36, 29 July 2006 (UTC)

[edit] Condensing bios

Good work on the bios in People in systems and control. Currently, the historical figures are presented as a dense list, and it would be nice to see the active researchers bios condensed as well. It seems odd/absurd to be so verbal about the current researchers when the historical figures where groundbreaking, and the active researchers "just" "wrote a few books". I feel it would be good to condense the bios. I will gladly do so, given the go ahead. The goal would be to have them down to 1 line of text in most browsers/resolutions, like the historical figures. Agree/Disagree? jugander (t) 17:34, 8 August 2006 (UTC)

OK. But I am worried about shortening it too much. It seems to me the word "professor" could be omitted in each case, but I would leave the name of the university, for example. In the beginning each person had literally just the name and it was difficult for the causal reader to have any idea who these people were and why they are mentioned. Ultimately though, I agree with you. Encyclops 17:51, 8 August 2006 (UTC)

[edit] Kolmogorov equations

Thanks of the clear up on those! jugander (t) 06:11, 15 August 2006 (UTC)

[edit] Hamiltonian

At the end of the article on Hamiltonian (control theory), you mention that in discrete time the costate variables have to be considered a timestep ahead of the state variables. It's not particularly clear why this is - could it be explained quickly, or referenced? Helmut Ahab 00:35, 7 September 2006 (UTC)

It is a notational convention, not a deep result. I have added a small explanation. Encyclops 00:25, 8 September 2006 (UTC)
Thanks for that. 128.250.102.134 00:49, 26 September 2006 (UTC)

[edit] Statistical Arbitrage

In my humble opinion, Statistical arbitrage is more within the scope of something like WP:WikiProject Finance than WP:WikiProject Statistics. It is a topic in Finance (or Mathematical Finance) having some statistical aspects, rather than a mainstream Statistics topic. Encyclops (talk) 17:58, 22 April 2008 (UTC)

See Wikipedia talk:WikiProject Statistics#Things on boundary of scope. My thought was that Statistical arbitrage did involve some statistical thinking in setting up the method. At present WikiProject Statistics is trying to bring all articles on statistics topics into the list of statistical topics to provide a basis for further progress. You might want to look at the project page and consider joining. Melcombe (talk) 18:11, 22 April 2008 (UTC)
