Hi, I'm having some trouble with R code for one of my assignment questions on transforms. I've never used R for transformations so I'm not sure where to being. Our prof did give us some partial R code.par(mfrow=c(2,2)) plot(X[,2],e) plot(X[,3],e) plot(X[,4],e) plot(X[,5],e) Any help ?? 3. Try the following transformations on the response variable: (a) ? y = ey (b) ? y = log(y) (c) ? y = 1/y (d) ? y = 1/y2 (e) ? y = 1/?y Carry out the regression ? y = ?0 + ?1 x1 + ?2 x2 + ?3 x3 + ?4 x4 + ? for each case, including the residual analysis
This mailing list specifically discourages homework questions, but especially discourages ones where the student remains anonymous and show not evidence of prior effort beyond typing the question at their keyboard.
