In this video I cover hypothesis testing of a linear combination of regression parameters in the Matrix Formulation of the Linear Regression Model. • I talk about the derivation of the mean and variance of the linear combination of parameters and how we can arrive at a new test statistic that will still follow the t-distribution. • #MLR • #Regression • #Hypothesis • 0:00 Revision • 0:35 Introduction • 04:40 Mean and Variance of the Linear Combination • 06:44 Hypothesis Testing • 09:15 Example problem
