2. In an experiment involving one dependent variable y and four explanatory variables 1₁, 12, 13 and 14, all possible regressions are fit to the data set consisting of n = 13 cases. A constant term is routinely included in all models. The results are summarizes as follows: Regressors in Model Residual Sum of Squares None 4073.6 I1 1898.5 I2 1359.5 2909.1 I3 IA I1, I2 X1, X3 I1, I4 I2, I3 I2, Is 1325.8 86.9 1840.6 112.1 623.1 1303.3
