# Perl advantages in data management/statistical analysis?

I've frequently read that knowledge of Perl or Python complements SAS or R, and seen that Perl is a desirable language in job advertisements.

Can anyone clarify this a bit more? Is Perl limited to text mining & database updates or does it have other applications in the statistics world? Thanks!

Since Python was discussed enough on CV, I took the liberty to focus this Q on Perl. –  mbq Sep 7 '12 at 17:28
Roger, thanks @mbq. –  RobertF Sep 7 '12 at 18:49
This doesn't seem like a CrossValidated question (it's about computing rather than statistics), but I'm not quite sure where it does belong ... –  Ben Bolker Sep 7 '12 at 19:11
Hopefully, @Karl (website) or Vincent Zoonekynd (website) will come to rescue here; otherwise, check this JSS article: Using Perl for Statistics: Data Processing and Statistical Computing. –  chl Sep 7 '12 at 20:11
Thank you @chl! –  RobertF Sep 14 '12 at 14:34

I once used python to fit a specialized GLM with $> 500$ million observations and an a priori unknown number of parameters. It would have been impossible to do in R, in a number of respects, and the statistical needs were far from light, indeed they were the integral aim of the utility. :-) –  cardinal Feb 14 at 3:25
