Is your function still correct? If so, use your function to generate values of y for which √ y = 3x + 2 + xε where x takes 1001 equally spaced values in the interval [0, 1], and ε is standard normal. The above function will give correct results when the mean and sd parameters are vectors of length n. They do not need to be constant vectors. > x <- seq(0,1,length=1001) > y <- rnormBM(1001, mean=3*x+2, sd=sqrt(x)) 4.
