looking for a webinar about solar ratio

Hi :)

For a few years back I watched a webinar about solar ratio. I remember it contained regresssion analysis, but also data extraction by use of dataset analysis. I want to watch it again.

Can somebody post a link for it here. The problem is that on the Matlab site, the webinars are continously removed, so I cant find the webinars that I watched for a few years back on the site where the webinars are supposed to be.

Thanks!
