About Regression Modelling questions. And please use R for all of the regression analysis. Thanks. The textbook I used is "Applied Regression Analysis, 3rd Edition" by Norman R. Draper and Harry Smith. The photos of the questions and the pdf of text book will be attached. Chapter 1: Fitting a Straight Line by Least Squares, Sections 1.1–1.5 , Chapter 2: Checking the Straight Line Fit, Sections 2.1–2.6 and Chapter 4: Regression in Matrix Terms: Straight Line Case, Sections 4.1–4.5 maybe helpful for you. The class notes will also be attached to help you answer the questions. Thanks. Please pay attention, I have finished question 1, question 3 and the part (a) to part (d) of question 2. For the part (e) to part (h) of question 2, I have no idea, please help me to solve them. And please help me to check the answers of those questions that I have solved, if there have some errors please help me to fix them, thanks. After I accpted the answers, I will give the amount of $40 as tips. Thanks.
