Additionally, we make an assumption about the form of the relationship between x and y. We assume that the relationship between x and y is: as the values of x get larger, the ability to predict y becomes less accurate. - Answer -Suppose a residual plot of x verses the residuals, y ŷ, shows a nonconstant variance. In particular, as the values of x increase, suppose that the values of the residuals also increase. This means that: the value of the correlation. - Answer -In a regression analysis, an outlier will always increase:
