To estimate the 3 parameter weibull distribution, matlab needs start values. You can read here:
I am generating random numbers with 3 parameter weibull distribution and estimating them with MLE.
For that, I need to give start values.
params = mle(data,'pdf',custompdf,'start',[5 5 5],... 'Options',opt,'LowerBound',[0 0 -Inf],'UpperBound',[Inf Inf min(data)])
Does anybody tested different startvalues? I tested a lot of start values. I used "rng(default)" to have the same "random" numbers every run and checked the results, if something changes.
Sometime the results changes a little bit, sometimes nothing changes. So do someone checked the startvalue much more accurate?
