Data transformation and standardization The Logit transform is primarily used to transform binary response data, such as survival/non-survival or present/absent, to provide a continuous value in the range (‑,), wherepis the proportion of each sample that is 1 (or 0). The inverse or back-transform is shown aspin terms ofz. This transform avoids concentration of values […]
