Analysis of proportional data in reproductive and developmental toxicity studies: comparison of logit transformation, arcsine square root transformation, and nonparametric analysis
We conducted power calculations to compare different approaches (nonparametric, arcsine square root-transformed, logit-transformed, untransformed) for analyzing litter-based proportional data.  A reproductive toxicity study with a control and one treated group provided data for two endpoints: prenatal loss, and …
