Residual sum of squares for dose-response models

Calculates and displays the residual sum of squares (RSS) for a fitted dose-response model. For models with multiple curves, per-curve and total RSS values are returned.

Usage

rss(object, print = TRUE)

Arguments

object

an object of class 'drc'.

print

logical. If TRUE (the default), the RSS values are printed.

Value

Invisibly returns a matrix of RSS values. For single-curve models, a 1x1 matrix. For multi-curve models, includes per-curve values and a total RSS.
