Description
nlr2 calculates a nonlinear R-squared for the observed values.
Usage
1
nlr2(observed, expected)
Arguments
observed
a numeric vector of observations.
expected
a numeric vector of expected values.
Details
This function calculates the non-linear R-squared. The equation used is:
R^2 = 1 - (SS_reg / SS_tot)
(see p. 34-35
here).
Note that this nonlinear R-squared is not anything squared so it can result
a negative value. Negative values indicate poor model fit.
Value
The nonlinear R-squared value (numeric scalar).
