Hey
I have 2 columns of data (A and B) which follow independent Weibull distributions with a common shape parameter (γ) and with parameters (αA, β, γ) and (αB, β, γ). Prior to parameter estimation, I would like to fix the β at -0.5 (JMP is not allowing negative β).
Please guide how do I calculate these parameters for Weibull distribution using both Least Squares and Maximum Likelihood method while fixing β as -0.5. If not Least Squares, Maximum likelihood method would be fine.
I also want to calculate Γ for both of my data sets. Please guide on that too.
Thanks
