Description
What is this formula?
This formula models a power law relationship where one variable changes proportionally to a power of another variable.
When to use it
Use this formula when analyzing nonlinear scaling relationships between physical, biological or statistical quantities.
Example
For:
a=3
n=2.5
x=4
y=3*(4^2.5)
y=3*32
y=96
