I PLS Question 4 You estimate a linear model of the form y=xte in R. The matrix X is a n by p matrix, and y is an n by 1 matrix. You call the result "fit." Which of the following is returned by the command fit$residuals? A histogram of the values of X%*%beta.hat, where beta.hat is a p by 1 matrix of the estimated coefficients A vector containing the values of y-X%*%beta.hat, where beta.hat is a p by 1 matrix of the estimated coefficients A vector containing the values of X%"%beta.hat, where beta.hat is ap by 1 matrix of the estimated coefficients O A histogram of the values of y-X%*%beta.hat, where beta.hat is a p by 1 matrix of the estimated coefficients
