Hello,
I am looking at the relatively small dataset and comparing the survival of 2 groups of mice.
The end survival is not very difference but it is mostly the hazard ratio which is not very consistent, one group showing a higher ratio in the earlier time.
I went for Gehan-Breslow-Wilcoxon but someone is suggesting a Cox regression.
I cannot see why it would be better but I might be missing something something, help please?
Thanks!
