Hi, I have a question on Assignment X2 question 1 According to Q.1, mu75 is 0.02, mu76 is 0.04 In the solution, 4p75 is calculated as exp(-0.04*4), i.e. exp[-(mu76 + mu77 + mu78 + mu79)] However, according to CMP ch7, P.33 4p75 should be calculated as exp[-(mu75 + mu76 + mu77 + mu78)], i.e. exp(-0.02-0.04*3) Am I missing anything? Thanks for help!
Hello Remember that age is continuous, so the force of mortality from age 70 to 75 is 0.02 but then from just above 75 to 80 is 0.04, as used in the solutions. Hope this helps! Andy
