Hi,
I need to fit a series of data points(1000) using a 3 parameter Weibull distribution. Can I get some help?
Thanks

Use MATLAB's "mle". Therein, supply pdf and cdf of the 3-parameter Weilbull distribution as a custom distribution.
Best wishes

The question is how to get the 3 parameters in order to be able to use them with the mle function?

Which three parameters ?
Give senseful values for a, b and c in the vector "start". After the call to mle, phat will contain the optimal parameters ahat, bhat and chat (deduced from your vector "data").
Best wishes
