Exponentially interpolate around two data points
1 | interpolate_exponential(p1, p2, t1, t2, t0)
|
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) |
This function first calculates the implied exponential growth rate between two points, and then predicts where the function would be in the intermediate year.
