Thanks for the advice. Like I said, I am still pretty new to R, and stats
in general. I tried wading through the search results on google, but I
didn't really find anything that I could understand. I am working with
percentages as my dependent variable, and I am trying to get my
distribution as close to normal as possible. Is an arcsine transformation
even the correct choice for my data? Querying R for help usually leaves me
even more confused, so I was hoping someone could help me out by walking me
through the process.
Transforming proportions is something which people involved in
meta-analysis of non-comparative studies often do. You might like to
look in the manual for metafor (on CRAN) and the function escalc
which has a range of options under non-comparative studies. You might
also look at betareg (on CRAN).
I think you also need to find some local statistical support as your
question is now less about R and more about statistics.
