I have managed to perform a two parameter weibull analysis on my data which provides me with the shape parameter and the scale parameter along with the confidence intervals on these parameters. In order to do this I have been using wblfit() is it possible to modify wblfit() so that it will provide me with the location parameter?

I have read through this demo here: http://www.mathworks.co.uk/products/statistics/demos.html?file=/products/demos/shipping/stats/cdffitdemo.html

But I still cannot get matlab to do what I want it to do.

Thanks in advance, Matt

I forgot to mention that the location parameter for my dataset is likely to be negative, also I would like to use least squares (X on Y) rather than MLE
