Program to fit data to normal distribution function

[rawi]

Hi Namir,

Thank you for your interest and your friendly word.
I wanted to attach the raw-file to the post but did not realize that raw-files are not accepted as attachments. So I added a link to a Dropbox at the end of the original post, I hope that works. Furthermore I improved the program and added the possibility to estimate Y for a given X. This is included in the original post.

Best

Raimund
