Run the CROSSVALIDATION2 program with 5 replications using an original sample size of 500. Record the regression weights and R-square values for eachsample of size N = 250. Record the regression weight and R-square value for the original sample.

a. Sample (N = 500): Regression Weight ________ R-Square _________

b.

c. The regression equations for sample A and sample B are computed indepen-dently. Are the R-squared values similar in sample A and sample B for the fi ve replications? YES ______NO ______.

Q94:

Run the CROSSVALIDATION2 program with 5 replications having an original sample size of 1,000.

a. Compare the regression equation results for the original samples of N = 500 and N = 1000. Record the SAMPLE regression weights and R-square values. N = 500 Regression Weight________________ R-square _________ N = 1000 Regression Weight________________ R-square _________

b. Does sample size affect the R-square value? YES ______NO ______.

c. Which sample size would give better estimates of R-square and the regression weight? N = 500 ________ N = 1000 ________
