:::: Ah, well the connection between the two wasn't spelled out to the satisfaction of my (possibly caffeine-deprived) mind. And, as far as I can tell, the online algorithm does not easily merge statistics from multiple populations, but rather updates the statistic one sample at a time. Correct me if I am wrong, or please add a suitable method to the page. [[Special:Contributions/209.237.23.36|209.237.23.36]] ([[User talk:209.237.23.36|talk]]) 22:56, 13 May 2009 (UTC)
==Pseudocode==
The numerically stable mean and variance computation works, but attempting something similar for skewness and kurtosis using the incremental moments computation code in the later section seems to fail. IIs maysomething bemissing Iin amit missing? somethingAre there any reference implementations ..? [[User:Shyamal|Shyamal]] ([[User talk:Shyamal|talk]]) 16:17, 14 July 2009 (UTC)
