Assume that the samplefollows the linear model (9.6.1). Suppose Y0 is a future observation at and we want to determine a predictive interval for it. Assume that the model (9.6.1) holds for Y0; i.e., has adistribution. We use _0 of Exercise 9.6.6 as our prediction of Y0.

The pdf depicted in Figure 7.9.1 is given by where (the pdf graphed is for m2 = 0.1). This is a member of a large family of pdfs, log F-family, which are useful in survival (lifetime) analysis; see Chapter 3 of Hettmansperger and McKean (2011). (a) Let W be a random variable with pdf (7.9.2). Show that W = log Y , where Y has […]
