I generated a dataset from a known Weibull distribution: Weibull( alpha= A.SI^-n, beta) where A=1800, n=0.5, Beta=1.5, and SI=1000. Here is the link of the dataset (DF1). I tried to estimate the parameters of the distribution in a Bayesian analysis using PYMC3 and below is my code. The Bayesian esti…

Isn’t that constant and independent of the model parameters?

Also, if I understand correctly, both A and n here (but not SI) are parameters of the model. Are you sure the model is not degenerate (multiple pairs of A and n give the same result)?
