- wrie down the estimated regression equation?Suppose that R2= 1 for a data set. What can you say abota. SSE? b. SSR? c. the utility of the sample multiple linear regression equation for making predictions?Suppose you wanted to test whether or not the payoff to an additional year of education was the same for men and women in the STEM majors. How would you set up your regression analysis in this case
- How many predictors are in this regression?When trying to decide whether to use the Linear Regression or the Exponential Regression of a set of data, what statistic should I use, and how do I use it?Calculate the estimated R2 and state why we should consider using adjusted R2 instead of R2 in the setting of multiple linear regression?
- 27. Using the stepwise regression, what is the value of adjusted R2 of the last step?a) Give a practical interpretation of the y-intercept of the regression line. b) What is the best-predicted value for the median hourly wage gain for the fifteenth year of schooling? c) The actual wage gain for the fifteenth year of schooling was 14%. How close was the predicted wage gain present to the actual value, i.e. what is the residual?Find the equation of the regression line for the given data. Round values to the thousandth
