We consider both parametric and nonparametric statistical analyses of survivorship curves and of removal rates, including assumptions, tests, ecological applications, and the difference between censored and uncensored survival data. For censored data, the Gehan—Wilcoxon test, the longrank test, and the likelihood ratio test and appropriate and are readily available in mainframe computer statistical packages. In cohort analyses, these tests can determine if cohorts of different ages have different age—specific death rates or different death rates over the same time period.
