If I simulate data for 1000 times from Weibull (a,b) distribution with a is shape parameter and b is scale parameter for different combination od parameters to calculate maximum likelihood estimates (MLEs) for a and b. How the initial values for a and b that needed to calculate MLEs can be specified. For example, If I generate from Weibull(24, 4) and Weibull(12,4) to calculate MLEs, what are the suitable initials for both parameters in the two simulations? Thank you.
