Cuzick–Edwards test

The Cuzick-Edwards test is a statistical method often used to assess the relationship between an ordinal categorical variable and a continuous or count variable, particularly in the context of epidemiological and clinical research. This test is typically applied when researchers are interested in testing for trend effects across ordered categories. One of its primary applications is in survival analysis and longitudinal studies, where researchers may want to evaluate whether there is a systematic increase or decrease in an outcome measure as an ordinal predictor variable increases.
