### What is the minimum of 2 Weibull distributions with the same shape parameter

If X and Y are two independent Weibull distributions with the same shape parameter, what distribution is the min(X, Y). I am trying to find out the hazard ratio for the following case. If I model Z=...

### How can I calculate the α and β parameters for a Beta distribution if I know the mean and 95% upper boundary I want the distribution to have? [duplicate]

As an input I have the mean (expected value) of a probability and the 95% upper bound. Now, I would like to define the α and β parameters for a Beta distribution such that I can do Monte Carlo ...
