is an average. An average is never greater than the largest component. If you look at the graph, the blue curve is clearly the sum of the component curves. Zik 03:40, 5 March 2006 (UTC)
- You are right, I fixed the caption. I have no idea how I had missed that. :) Oleg Alexandrov (talk) 01:09, 6 March 2006 (UTC)
[edit] name
In my experience calling the technique Parzen windowing is limited specifically to time-series analysis, and mainly in engineering fields. In general statistics (and in statistical machine learning), the term kernel density estimation is much more common. Therefore I'd propose it be moved there. As an aside, the attribution to Parzen is also historically problematic, since Rosenblatt introduced the technique into the statistics literature in 1956, and it had been used in several more obscure papers as early as the 1870s, and again in the early 1950s. --Delirium 22:59, 26 August 2006 (UTC)
[edit] x
What is x in the equation? --11:06, 5 October 2006 (UTC)
- It is a real number, I guess. Oleg Alexandrov (talk) 02:55, 6 October 2006 (UTC)
[edit] Changing the name of this page
The technique called here Parzen window is called kernel density estimation in non parametric statistics. It seems to me to be a much more general term and much clearer for people searching for it. The comment above state the same problem. I also agree that the article should refer to the Parzen-Rosenblatt notion of a kernel, and not just of Parzen. The definition of a Parzen-Rosenblatt kernel should be latter added on the kernel (statistics) page. —The preceding unsigned comment was added by Gpeilon (talk • contribs).
- That's fine with me. If you move the page, you should also fix the double redirects. That is, after the move, while viewing the article at the new name, click on "what links here" on the left, and any redirects which point to redirects need to be made to point to the new name.
