Arcsine or angular transformations have been used for many years to transform proportions to make them more suitable for statistical analysis. A problem with. The Rationalized Arcsine Transform linearizes the proportions and converts them to “rational arcsine units”. The linear tests can then be performed on the RAU. RAU(X,N) transforms the number of correct responses X to the % rationalized arcsine (rau). N gives the number of repetitions. %.
