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
