Question:
A regression model with K = 16 independent variables is fit using a panel of sevenyears of data. The sums of squares for the seven separate regressions and the pooled regression are shown below. The model with the pooled data allows a separate constant for each year. Test the hypothesis that the same coefficients apply in everyyear.
