R-squared for dose-response models

Source: R/Rsq.R
Rsq.Rd

Calculates and displays R-squared values for a fitted dose-response model. For models with multiple curves, per-curve and total R-squared values are returned.

Usage

Rsq(object)

Arguments

object

an object of class 'drc'.

Value

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

Details

R-squared is computed as \(1 - RSS / TSS\) where RSS is the residual sum of squares (obtained via rss()) and TSS is the total sum of squares.

See also

rss() for the underlying residual sum of squares.
