WebSAS. To conduct a Brewlosw-Day test in R you can use BreslowDayTest () from the DescTools package. BreslowDayTest () requires a 2 x 2 x k table as its main argument; you can also specify an odds ratio for the null hypothesis (if not specified, the Mantel-Haenszal OR will be used). To create 2 x 2 x k tables from a data-set you can use xtabs ().

In medicine, Breslow's depth was used as a prognostic factor in melanoma of the skin. It is a description of how deeply tumor cells have invaded.
