3) Define the significance level of a test, and the two kinds of errors associated with testing. 4) What is simple linear regression? 8-11/50 Part 8: Hypothesis Testing Test a Hypothesis About a Coefficient 8-12/50 Part 8: Hypothesis Testing Classical Hypothesis Testing We are interested in using the linear regression to support or cast doubt on the validity of a theory about the real world counterpart to our statistical model. One of the main objectives in linear regression analysis is to test hypotheses about the slope (sometimes called the regression coefficient) of the regression equation. We will use a generalization of the F-test in simple linear regression to test this hypothesis. 9 Under the null hypothesis, SSR/ 2 2 p and SSE/ 2 2 n (p1) are independent. This chapter starts with the introduction to a linear regression analysis, estimation and inference methods.The OLS test statistic for testing this hypothesis (also called t-statistic) is. which is asymptotically distributed N(0 1) under the null hypothesis. 2 The Idea For hypothesis testing in the linear regression context is the same as always: 1. we formulate the null and alternative hypotheses that were interested in testing, and choose a level of signi cance for the test.
