calc_exprate: Calculate exponential growth rate

In pbsag/swimr: Functions for Looking at Swim

Calculate exponential growth rate

Description

Calculate exponential growth rate

Usage

calc_exprate(p1, p2, t1, t2)

Arguments

p1	Value in period 1
p2	Value in period 2
t1	Time step for period 1 (i.e., 2010)
t2	Time step for period 2 (i.e., 2040)

Details

This function calculates an annualized exponential growth rate implied by measuring a value in two different time periods. Solves the elementary exponential growth equation,

p_2 = p_1 e^{r(t_2 - t_1)}

for r.

Examples

calc_exprate(10, 12, 2010, 2040)
