[Eeglablist] Balanced ANOVA for power spectra

[Dr Cyril Pernet]

Hi Marina,

I'm not sure why the analysis fails, but if you use a hierarchical 
approach (model trials per subjects, within subject/between trials 
variance -- then do the ANOVA of the parameters, between subject 
variance), there is no issue conducting such analysis -- all of it can 
be done with the LIMO EEG plug-in 
(https://urldefense.proofpoint.com/v2/url?u=https-3A__limo-2Deeg-2Dtoolbox.github.io_limo-5Fmeeg_&d=DwIDaQ&c=-35OiAkTchMrZOngvJPOeA&r=kB5f6DjXkuOQpM1bq5OFA9kKiQyNm1p6x6e36h3EglE&m=UsBuMcooCrjeVh-rAcdQnaKyG-MG7T-x4YC1UwCF9iAJUqjC-xoJgrcM4Kfsyt4V&s=905fWcQK5VyRCKfTEP-8-IN93uoPA8KtBkt3gYx7QCQ&e= ) than you call from STUDY.

You can install the plug-in from Github (latest fixes) or more the 
plug-in manager (few months old)

> Good morning,

> I would like to analyze the power spectra of some waves for 2 different conditions (within-subjects) and 2 different groups (between-subjects). However, when I ask the program to do that I can see in the script the following sentence “Possible mixed paired and unpaired independent variables, using balanced Anova (which assumes all unpaired)”. I would like to know which are the implications of using balanced Anova that assumes all unpaired if I have truly paired data in my data.
