HR: Worksheet 8.

Worksheet 8 involved the regression analysis. Multiple-regression analysis can compare different variables’ effects. The coefficient, t-statistic, and p-value are important tools in the regression analysis. There was also a question in Worksheet 8 that required a correlation matrix. The matrix contains all the selected variables, and of course each variable correlates as a “1” to itself and between 0 and 1 for the other variables.
