Web5.2 Confidence Intervals for Regression Coefficients. As we already know, estimates of the regression coefficients \(\beta_0\) and \(\beta_1\) are subject to sampling uncertainty, see Chapter 4.Therefore, we will never exactly estimate the true value of these parameters from sample data in an empirical application. However, we may construct confidence …
