We discussed problems 4, 8 and 9 from Chapter 4, and we did an exercise in Stata discussing the output.

We worked in Stata on an application illustrating how to obtain confidence intervals for the predicted y (the conditional mean of y given the regressors are equal to a certain value) and the future y conditional on some characteristics. We discussed how to obtain a prediction of y (the conditional mean) when we regress log(y) on regressors. We then discussed about different forms of (non)linearity, in particular about having quadratic regressors in a regression.

We discussed how to test for multiple linear restrictions and the different ways of calculating the F statistic. We then discussed how to build a confidence intervals for the conditional mean of the dependent variable as well as for an unknown outcome of the dependent variable.

We practiced OLS estimation in Stata as well as how to create new variables needed for the OLS estimation. We interpreted the output from Stata following the OLS estimation. We performed t-tests (one-sided, two-sided) and calculated confidence intervals in different applications.
