QMB Final Exam multiple choice SolvedThe least squares method of simple linear regression minimizes which of the following?a. SSRb. SSEc. SST - ANS-b. SSEif the Durbin-Watson statistic has a value close to 0, which assumption is violated?a. normality of errorsb. independence of errorsc. homoscedaticityd. none of the above - ANS-b. independence of errorsthe standard error of the estimate if a measure of:a. the total variation of the Y variableb. the variation around the simple regression linec. explained variationd. the variation of the X variable - ANS-b. the variation around the simple regression linethe coefficient of determination tells us:a. that the coefficient of correlation is larger than 1b. whether r has any significancec. that we should not partition the total variationd. the proportion of total variation that is explained - ANS-d. the proportion of total variation that is explainedin performing a regression analysis involving two numerical variables, we are assuming:a. the variances of X and Y are equalb. the variation around the line of regression is the same for each X variablec. that X and Y are independentd. all of the above - ANS-b. the variation around the line of regression is the same for each X variableif the correlation
