interpolate_exponential: Exponentially interpolate around two data points

In pbsag/swimr: Functions for Looking at Swim

Exponentially interpolate around two data points

Description

Exponentially interpolate around two data points

Usage

interpolate_exponential(p1, p2, t1, t2, t0)

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)
t0	The timepoint for interpolation (or extrapolation)

Details

This function first calculates the implied exponential growth rate between two points, and then predicts where the function would be in the intermediate year.
