Title: Statistical Model of LongTerm Disability
Abstract: Statistical models are commonly used in the insurance industry, and longterm
disability benefit reserving is one of them. When an insured is injured and disabled,
his/her insurer would like to know how much is needed to pay disability benefits for
this claimant, especially longterm disability benefits in case of severe injury, and the
amount of benefits depends on how long the insured will stay disabled, in other words,
the probability of recovering from disability. A statistical model is built based on historical
data, with consideration of credibility. Interpolation and other mathematical method are
used to derive model for different groups of disabled. A hypothesis test is used to evaluate
the validity of model. In this seminar, I will cover all the steps and relevant issues in the
project.
Coffee and cookies will be served prior to the lecture at 12 o'clock noon
