Good Morning Everyone, or whatever time of day it is. I have talked myself into a circle and I'm not sure which path to follow at this point. So, I thought I would ask the experts. What I am trying to do is determine if there is a statistically significant difference in the time it takes to reach a diagnosis based on the result of the diagnosis. For example, does it take significantly longer to reach a final diagnosis based on whether a tumor is malignant or benign. Calculating the median number of days to final diagnosis I believe I have figured out successfully. But then I have found myself a bit stuck. I considered ANOVA but the time data violates the independence assumption. I considered proc lifetest, conducting a peto test, and probdf but I'm uncertain which to use in this scenario. Any guidance would be helpful. Thanks
