As you see the estimated values for b2 , b3 and b4 are the initial values of
them. The log-likelihood value did not change!

Wrong. Nabble lies. It is not the Rhelp Archive and this message was sent from

Dear R-helper,
I am trying to do maximum likelihood estimation in R. I use the optim
function. Since I have no prior information on the true values of the
parameters, I just randomly select different sets of starting values to feed
into the program. Each time, I get the following error
that worked out well, thank you again!
I also tried to use lm, and as expected in this case, I almost got the same
estimates of the parameters as in the MLE-case.
Best Regards
Henrik

Hey Henrik
I dont do MLE myself but this recent blog might be helpful.

Try survreg(), in the survival package.

I'm trying to calculate the Maximum likelihood estimators for a dataset

I started by using the function nlm, but isn't there a separate method
for doing this for e.g. the weibull and the log-normal distribution?
Thanks,
