I don't know much about GLM in general or glm in R. Can anyone tell me
how to do the following (in R or some other stat system) or refer me to a
textbook discussion?
Two factor ANOVA repeated measures design.
Each subject gives a percent correct.
I am assuming the correct way to proceed is to fit a generalized linear
model with binomial responses and logistic link. But I have not found a
detailed discussion of this in either McCullagh & Nelder or Dobson.
Here is a toy example. Each datum is proportion correct out of 100
trials for one subject:
b1 b2
a1 .5,.6 .1,.2
a2 .7,.8 .2,.3
a3 .8,.9 .3,.4
(2 subjects)
How does the analysis proceed? Thanks very much for any help.
