I am doing a Kaplan-Meier analysis comparing 2 treatments. I have been asked to provide the median difference and corresponding 95% confidence interval for the survival times. The standard output appears to only provide the medians and 95% CIs for each treatment, but not the difference between the treatments. Is there a way to do this in SAS?
ANOVA, or Analysis Of Variance, is used to compare the averages or means of two or more populations to better understand how they differ. Watch this tutorial for more.
