1. ### Power analysis for GEE

I am designing a study that would require using GEE (generalized estimating equations) to analyze repeated measures of a dichotomous variable. Is there a way to estimate the sample size required for this analysis? Thank you!
2. ### How to analyze dichotomous DV with between- and within-subjects factors?

Hello everybody, I am designing a study and need to make sure I'll be able to analyze the data (or else I will modify the design). For the analysis, I would have a dichotomous dependent variable (correct/incorrect) and 3 factors. One of the factors is age group, a between-subjects factor with...
3. ### Mcnemar's test for dichotomous IV vs. dichotomous DV: how pertinent is it?

4. ### Dichotomous DV and 3 points of measurement per condition within each subject

I have been reading a lot on this site and I think I am going to analyze my data using a mixed model ANOVA- random effect= subject and 2 fixed effects- comparison and pricing (each have 2 levels). All of my subjects were in all 4 conditions (a cross between the 2 factors) and answered 3 items in...
