I work with a federal agency that has not provided many details of their analysis (we ask, they don't provide it). When we asked what method they were using for a statistical control they responded 'Fixed effect model?" I understand the difference between random and fixed effects regression, but as best I can tell that is not what they are referencing. Anyone know what statistical method fixed effects models (aka regression apparently) is?

Methods

Fixed-effect model (state fixed effect):

Y = a set of individuals with disability characteristics variables from 1 to X and unemployment rate and industry data in state s year t quarter q plus a state fixed effect plus and error term. The results are generated with national data, we have only state data, they seem to run the results without an intercept and then add this state fixed effect to it. Any suggestions at all of what is occurring here would be appreciated. I have no idea what they are doing.

Their economic effects are particularly confusing, They generate the percent in a given industry (say industrial) in your state by quarter for customers. But if you use that to predict results you would be predicting with a constant.....

This article apparently provides details, but I can not access it.
