ELRF™ Enterprise: Actuarial Reserving Software
Available from Insureware Pty Ltd
The Extended Link Ratio Family (ELRF) modeling framework formulates average link ratio methods as regression estimators and extends them. This includes Mack (volume weighted averages), other weighted averages and extensions:
-Murphy (an intercept)
-A constant trend in the incrementals for each development period down the accident years
-Optimal combinations of intercepts, trends, and link ratios
-Control over variance assumptions (delta)
Standard deviations are computed analytically in all cases.
