Use the data "cheddar" in faraway package to solve the following question by showing the R code.
Thiry samples of cheddar cheese were analyzed for their content of acetic acid, hydrogen sulfide and lactice acide. Each sample was tasted and scroed by a panel of judges and the average taste score produced. Used the cheddar data from faraway package to answer the following: b) Compute the correlation between the fitted values and the response. Square it. Identify where c) Fit the same regression model but without the intercept term. What is the value of R reported d) Compute the regression coefficients from the original fit using the QR decomposition showing your Report the values of the regression coefficients. this value appears in the regression output. in the output? Compute a more reasonable measure of the goodness-of-fit for this example. R code Thiry samples of cheddar cheese were analyzed for their content of acetic acid, hydrogen sulfide and lactice acide.
