Hi Cary. I’m not sure which file you are looking at, but it is probably a version of files I have posted over the years starting around 2005. The list of factors is read by a script which does a ranking system performance test for that one factor then repeats the test for every factor in the list and saves the ‘bucket’ results for every factor to an Excel file. So you can see how the factor performs for the universe and date range used in the test. It was not a complete list even back then and doesn’t have all the good factors we have added lately. If I ever update it, I’ll post it.
This thread has a version of that file and a way to run it without knowing how to write any code:
FYI - the lines related to Estimates in this version of the file have a lot that fail because the factors were changed on the site and I never updated that file. The script will still run, but those bad factors will waste your API credits. Also, download the Excel file from that Google Drive location above if you want to see an example of the end result. Be sure to ‘enable content’ when you open it in Excel - then go to the Charts tab and the chart will change each time you select a different row/factor. This has been useful, but will probably be obsolete once AI is released.
