Question
T F In Simple Linear Regression test of hypothesis, beta_1 and rho have the same Test Statistic T F In Multiple linear Regression, R^2; and adjusted R^2 increase with the increasing number of X variables T F In partial F-test, the test statistic may contain (SSE, - SSE_t) or (SSR_f - SSR_r) T F In Simple linear Regression, t test and F-test of beta have the same p-value T F In MIR, the diagonal elements of (X'X)^1 are the standard errors of all beta, 6. In one-way ANOVA with K=6, how many possible pairs are there for Tukey's test ___________ In MLR with 6 independent variables and 28 data sets, what Is the C.R. (alpha= 0.05) of F test on "H_o: All beta, = o" ___________ In MLR with 6 independent variables and 28 data sets, what is the C.R. (alpha =0.05) of t test on "H_0: beta = 0" In one-way ANOVA with K=S, each n, =6, what is the degree of freedom of MSE ___________ What is the first step of data checking when doing a Multiple Linear Regression __________ In a multiple linear regression of five independent variables (X1 to X5) and 30 observations, the SST = 21217.1 and SSR = 13880.11. A reduced model of three variables (X2, X3, X5) from the same observations has SSE = 7933.14. Perform a partial F test with standard 5-step method.Explanation / Answer
