Details

These exhibits give some of the details behind the calculations producing the estimates of future values (a.k.a. "Reserves" in Clark's paper). Table65 works for both the "LDF" and the "CapeCod" methods. Table64 is specific to "LDF", Table68 to "CapeCod".

Table65(ClarkLDF(GenIns, maxage=20))
Table64(ClarkLDF(GenIns, maxage=20))

X <- GenIns
colnames(X) <- 12*as.numeric(colnames(X))
Table65(ClarkCapeCod(X, Premium=10000000+400000*0:9, maxage=Inf))
Table68(ClarkCapeCod(X, Premium=10000000+400000*0:9, maxage=Inf))
