By now, you have probably noticed that the regression in Table 2 has a binary dependent variable. Rather than using a probit, the author estimates a “Linear Probability Model” for the regression of RR on childbearing. First, fill in the right-hand side of the following equation for a linear probability model (referring to Table 2.

Stat 645 Homework 3 Solution Chapter 2 Problem 2.1 (a) If the SLR is appropriate, the conclusion is warranted. The confidence interval doesn’t include zero which provides evidence that the slope is greater than zero. Since the confidence level is 95%, the implied level of significance for the test is 5%.
There are many regression algorithms for the job. This exercise is about the very simple linear regression algorithm for prediction to give you an idea about the role of regression algorithms. Linear Regression Model and Least square solution.
