Table65: Functions to Reproduce Clark's Tables

Description

Print the tables on pages 64, 65, and 68 of Clark's paper.

Usage

Table64(x)
Table65(x)
Table68(x)

Arguments

x

an object resulting from ClarkLDF or ClarkCapeCod

Value

A data.frame.

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".
