Root-mean-squared-error of a fitted model
Calculates the root-mean-squared-error (RMSE) for objects of class nls, lm, glm, drc or any other models from which residuals can be extacted.
RMSE(object, which = NULL)
object |
a fitted model. |
which |
a subset of the curve to be used for RMSE calculation. If not defined, the complete curve is used. |
RMSE = √{\overline{(y_i-\hat{y}_i)^2}}
The root-mean-squared-error from the fit or a part thereof.

## For a curve subset. m1 <- pcrfit(reps, 1, 2, l5) RMSE(m1, 10:15)
