Group Insurance

1 Opinion from a Group Insurance Consultant in Texas.
For those interested in pricing and underwriting of group insurance this reference is a must. The previous editions have been used as the basis for seminars for years. I am using it myself as a tool for my underwriters. The techniques can be applied for Life and Disability Insurance and I am recommending it for my company reference library.

Proof techniques #1: Proof by Induction.

This technique is used on equations with "_n" in them. Induction
techniques are very popular, even the military used them.

SAMPLE: Proof of induction without proof of induction.

We know it's true for _n equal to 1. Now assume that it's true
for every natural number less than _n. _N is arbitrary, so we can take _n
as large as we want. If _n is sufficiently large, the case of _n+1 is
trivially equivalent, so the only important _n are _n less than _n. We
can take _n = _n (from above), so it's true for _n+1 because it's just
about _n.
