Post by: emeraldisle on Mar 10, 2018 A multiple regression model is assessed to be good if the error sum of squares SSE and the standard error of estimate s are both small, the coefficient of determination R2 is close to 1, and the value of the test statistic F is large.
Indicate whether the statement is true or false Q. 2 The width of a 95 confidence interval is 0.95. Indicate whether the statement is true or false Q. 3 In multiple regression analysis, when the response surface (the graphical depiction of the regression equation) hits every single point, the sum of squares for error SSE = 0, the standard error of estimate s = 0, and the coefficient of determination R2 = 1. Indicate whether the statement is true or false Q. 4 One can reduce the width of a confidence interval by taking a smaller sample size. Indicate whether the statement is true or false Q. 5 When an additional explanatory variable is introduced into a multiple regression model, coefficient of determination adjusted for degrees of freedom can never decrease.
