   ocr: Exploratory Distribution Plots Options on the check-mark pop-up menu displays exponential failure plots to graphically check the appropriateness of using t distributions for further regression modeling. Exponential Ploplots -log(Sur) by time for each group whe Surv IS the product-limit estimate of the survival distribution. that are approximately linear empirically indicate the appropr of using an exponential model for turther analysis. Weibull Plotplots log(-log(Sur) by logarithmic time for each ( where Surv is the product-limit estimate of the survival distribu Weibull plot that has approxim ...
