Estimates of direct effects (top value in each cell), and the p-values (bottom value) for the variables in each model, estimates of MSE and r-squares are given. The significant values are shown in bold. (^∗) The value of ${\hat{σ}}^{2} σ_{ε}^{2}$ is given instead of MSE. (^∗∗) The value of ${\hat{R}}_{PM}^{2}$ is given for the explained variation measure instead of r-square.
