(a) An econometrician estimates the following models: Y, = B.+B,X, +B,X, +u, and Y = B. +B,X, +B,X, +B,X, +v, where u, and v, are independent and identically distributed (iid) disturbances and X, is an irrelevant variable. Given this information, what can you conclude about the value of (1) R2 and (ii) Adjusted R?? Will it be higher in the second model than in the first model? (b) Using a hypothetical scatterplot of data for a regression model with R=0.94 and one for a regression equation with R2=0.48.
