How much would we expect 2 3 P IQ to change when brain size is increased one standard deviation (and height and weight are held xed)? How much would we expect P IQ to change when height is increased one standard deviation (and brain and weight are held xed)? How much would we expect P IQ to change when weight is increased one standard deviation (and brain and height are held xed)? Which predictor appears to have a greater impact on P IQ? 5. It is also possible to calculate the estimated standardized regression coecients b0 from the ordinary k regression coecients bk through the following relationship: Sxj b0 = bk k sy Fit the multiple linear regression model using the original response y = P IQ and the original predictors x1 = brain, x2 = height, and x3 = weight. Calculate the estimated standardized regression coeffcients using the output obtained here and the descriptive statistics output obtained above. Do your results agree with your previous results?
