Possible renaming

The title of this article is wrong. S-G 's paper also gave coefficients for numerical differentiation Petergans 16:48, 24 March 2007 (UTC)[reply]

Hi Peter,

Would you like to suggest a more appropriate article title? Perhaps I'm wrong, but I get the impression that you have access to the paper. I did not (and still do not) but rather came accross the filter in a sofware package. It filtered some data for me really well. I was so impressed I wanted to popularise the paper in some way. Comments appreciated etc...

I'd like to make a major ( by volume :) addition

I've done a significant amount of work on optimal computation and could use some help in getting it into wikipedia. First I'd like someone to review it! I do have a copy of the paper somewhere, and might add a synopsis of it to the main page if I can dig it up. Either of you interested enough to talk with me?

Order of derivative

The article says "Methods are also provided for calculating the first up to the fifth derivatives." Is there any particular reason this is limited to 5th derivatives? I would expect ill-conditioning at some order, but I would expect that to be hardware dependent, rather than a hard limit of 5. There are also limits where you should pick a higher-order fit polynomial for higher derivatives, but again, that's not a hard limit. My intro to this filter was from "Numerical Recipes in C", 2nd ed., sec 14.8. —Preceding unsigned comment added by 70.234.254.126 (talk) 18:44, 14 October 2009 (UTC)[reply]

example svp for the stupid ?

I looked at the fundamentals of statisitcs link; incomprehensible The anal chem papers are paywalled
