Which of the following statements is not true? 0 Plotting the tted or predicted values on the vertical axis versus the actual values on the horizontal axis is a diagnostic plot that can be used for assessing model validity and usefulness. O A normal probability plot of the standardized residuals is a basic plot that many statisticians recommend for an assessment of model validity and usefulness. 0 Provided that the model is correct, the residuals should be randomly distributed about 0 according to a normal distribution, so all but a very few standardized residuals should lie between -2 and +2 ( i.e., all but a few residuals are within 2 standard deviations of their expected value 0 l. O The regression model can be developed only when the dependent variable and independent variables are continuous
