Suppose you are interested in using the following multiple regression model to study the relationship between y and z, z2, zs,···, zk Though impossible to observe in reality, suppose you are able to gather a scatter plot of the variance of the error term, Var (ulz, za-.. ,z), against the first explanatory variable 1, holding all other explanatory variables constant. This scatter plot is shown on the following graph: Note: Var (u | 2, ) is denoted as Var (ula) on the vertical axis of the graph. x1 True or False: Given the scatter plot, there is evidence to suggest the model suffers from heteroskedasticity. True False
