pcrGOF: Summarize measures for the goodness-of-fit

Description

Calculates all implemented measures for the goodness-of-fit and returns them as a list. Works for objects of class pcrfit, lm, glm, nls, drc and many others...

Usage

pcrGOF(object, PRESS = FALSE)

Arguments

object

a fitted object.

PRESS

logical. If TRUE, the more calculation intensive $P^2$ is also returned.

Value

• A list with all implemented Information criteria (AIC, AICc, BIC, HQIC), residual variance, root-mean-squared-error, the p-value from neill.test (if no replicates), the reduced $\chi_{\nu}^2$ from fitchisq (if replicates) and the PRESS $P^2$ value (if PRESS = TRUE).

Examples

## single fit without replicates
## including PRESS statistic
m1 <- pcrfit(reps, 1, 2, l5)
pcrGOF(m1, PRESS = TRUE)

## fit containing replicates:
## calculation of reduced 
## chi-square included!
m2 <- pcrfit(reps, 1, 2:5, l5)
pcrGOF(m2)
