Hi! I am using 2015 edition of ST8. In chapter 18, section 5.2, Buhlmann Straub model, course notes(in page 37, below other assumptions, second point) states that "It then follows that , Vij * E(Xik/Theta i) does not depend on k. Should this not be "Vik * var(Xik/Theta i) does not depend on k, in line with the description given below?? Description says, "Similarly, the volume adjusted variance of the claims ratio(as a function of theta i) for a given risk does not vary from year to year". Or Am I missing something??? Any help is greatly appreciated. Thanks & Regds Subhasree
You're right, well spotted! We'll get a corrections document on the website. Thanks for letting us know. Ian
