Interpret the code from a Macro

[ADRostan]

I am trying to interpret the SAS code that is included in the attached Macro.  We are trying to validate this process and want to be able to replicate the actions taken by manually calculating the information. I would greatly appreciate your help or if you could forward me to another site, it would be greatly appreciated. See Below. Thanks so very much!!!

Please do not post text as binary files. 

Copy the text of the macro and past it into the window that pops up when you click on the Insert SAS Code icon on the forum editor menu bar.

Paste your code into a code block, it isn't long.

If you want to figure out what it does, go through it line by line and add comments to what you think each line is doing. Then go through it again block by block to isolate what each block is doing. I think this is an old method of moving regression, if you have SAS/ETS license this may not be required.

The code isn't particularly complex but this is typically where you would hire a consultant or SAS programmer for your conversion process.
