Tena koe I think you'll find the arcsine transformation is asin(sqrt(x/100)) where × is the percentage. However, it might be better to ask whether the data wouldn't be better analysed using generalised models (e.g., glm).

Thanks for your help! asin(x/100) ? or asin(x/100)*2/pi if you want the results rescaled to (0,1) curve(asin(x/100)*2/pi,from=0,to=100) ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
