2. The data (Assignment2-Q2.txt) include the total triglyceride level, in mmol/L(Y) and five potential predictor variables are defined as shown below. X1 : Chylomicrons X2 : Very low-density lipoprotein (VLDL) X3 : Low-density lipoprotein (LDL) X4 : High-density lipoprotein (HDL) X5 : Age of patient Consider the multiple regression model : Y; = Bo + B1Xi1 + B2X2 + Ej. Calculate parts (a) and (b) by hands. : == = = (a) Find r12 (b) Find (VIF), and (VIF)2. (c) What is the coefficients and MSE of the following models? i.
