The SAM web site will be upgrading Monday, May 23 from 4:00-5:00pm (Denver/mountain time). 

After doing a major change to our infrastructure, we have found a minor issue that we have corrected but will need to reboot the web site for it to take affect.

To make it as convenient as possible, we have scheduled it for Monday, May 23rd at 4:00pm (mountain). The process takes 15-20 minutes, but the site will only be unavailable for a short time. However, your session information will be lost (eg if you're writing a post, what you have written could be lost). 

SAM includes several features for analysis that involves comparing scenarios, optimizing input parameters, or more sophisticated parametric and statistical analyses.

The following series of short videos demonstrate how to use these features. They were made in an older version of SAM so the user interface looks slightly different than it does now, and the steps are the same or similar as in the current version.
