Dealing with proportions
Dear list,
I have very little experience in dealing with proportions, i am sure this is a very simple question but i could find no suitable answer beyond doing a chi-sq test and then using the Marascuilo procedure as a post-hoc analysis.
I am simply wanting to know if the proportions ( i.e the number of Yes / No) significantly differ between the cases and if so which cases are significantly high or low?
proportion <- structure(list(Case = structure(1:11, .Label = c("A", "B"...

- McNemar with unequal sample sizes
...ed case, like here:
after before
+ -
+ 10 14
- 5 53
So usually i use the mcnemar.test(stats).
Due to mortality, I now got the problem that my sample sizes in both
factors are not equal any more -- there are less cases in the "after"
condition. I already learned that Ekbohm (1982) and Marascuilo adressed
the problem conceptually, but I'm not that good at writing my own
functions.
Can anyone give me a hint what function/test/package in R to use?
Thank you very much for your help,
Christian
