WebbFIXED-EFFECTS REGRESSION . The fixed-effects model requires either the insertion of 17 (0,1) covariates to capture the unique effect of each of the 18 colleges (where each of the 17 dummy coefficients are measured relative to the constant term) or the insertion of 18 dummy variables with no constant term in the OLS regression. WebbWhen a treatment (or factor) is a random effect, the model specifications as well as the relevant null and alternative hypotheses will have to be changed. Recall the cell means model for the fixed effect case (from Lesson 4) which has the model equation Y i j = μ i + ϵ i j where μ i are parameters for the treatment level means.
