The object of the present study is to develop a statistical model that helps in estimating the survival time for Melanoma patients. We are using the data collected from the Surveillance Epidemiology and End Results (SEER) which contains 208143 patients with Melanoma between the years 1973 and 2008. The SEER records contain the survival time to the closest month, leaving us with a discrete type of random variable. The probability distribution function that characterizes the behavior of the survival time was found to be the Geometric distribution. This leads to developing a regression model with non-normal errors.
