Consider a response variable y. Let Fly ) =u be the mean of I, and suppose that the standard donation of I is proportional to a power of the mean of y, on all" We want to find a transformation on y that yields a constant variance . Suppose that the transformation Is a power of the original date, say s= yr. Then (@) Show that out ourta-I. (B) Give the power -tran sturmatim of y, where y Is a poisson with parameter " [pcy) = Muexp (t) ly!, y- 0, 1, 2, ,], which yield constant variance
