ANOVA comparison

[cheng...@monash.edu]

Dear MSstats team:

Wondering is it possible to compare more than 2 conditions at once? Not like in the manual, use average of 2 conditions (0.5 and 0.5).

Thanks a lot for your help.

Cheers

It's possible to do that - for example, if you want to compare between average of C2 and C3 and average of C1, (C3+C2)/2-C1 as formula, set ‘-1’ for C1, ‘0.5’ for C2 and ‘0.5’ for C3, and ‘0’ for rest of groups. See more details on page 19 of the manual

Hi Tsung-Heng:

Thanks for that.

I have seen that, but my case is I got 6 time points, can I do ANOVA to compare all the conditions together, instead of doing 2 at a time?

Dear Cheng,

You are asking about F test, correct? It is easy to do in principle, however we did not implement that (primarily because this is rarely requested). If you are familiar with linear mixed models, then you can output 'subject quantification', and use this as input to the mixed model and the F test. Sorry for not being able to help more directly.

Sincerely
