Hi guys, I would like to compare reaction times for a series of
experimental conditions. My data comes from ~100 trial repetitions over 10
participants (yielding ~1000 trials). I was told that just doing an ANOVA
on this dataset would be improper, because the 1000 measurements are not
truly independent - and that the proper way to do this is called a repeated
measure ANOVA.
I have tried to look for a scipy function for this and found nothing. In this
relevant discussion<http://scipy-user.10969.n7.nabble.com/stats-repeated-measures-ANOVA-td15997.html>a participant pointed the following out:
"Repeated measures" ANOVA is just a misnomer for using the "randomized
> block design" as a substitute for not knowing MANOVA or Hotelling's T-
> square test, and as such leads to conclusions that are very hard to
> interpret. The real value of repeated measures ANOVA in medical
> litterature is often to inform the reader that the authors don't
> understand the statistics they use ;-)
I would like to know whether I'm looking for the right thing at all, and if
yes how I could accomplish this with scipy
