estimateAIC {basicdrm}

Estimate Akaike Information Criterion

Description

Estimate Akaike Information Criterion

Usage

estimateAIC(resid, npar)

Arguments

resid

A vector of residuals from a given fit

npar

The number of paramters in the model

Value

The Akaike informtion criterion (AIC) value for the fit

Examples

conc <- c(0,2^(-6:3),Inf)
hpar <- c(1,3,0,75)
response <- evalHillModel(conc, hpar) + rnorm(length(conc),sd=7.5)

hfit4p <- fitHillModel(conc,response,c(1,2,3,4),start=c(0.5,1,0,100))
hfit3p <- fitHillModel(conc,response,c(1,2,4),start=c(0.5,1,0,100))

aic4p <- estimateAIC(residuals(hfit4p),4)
aic3p <- estimateAIC(residuals(hfit3p),3)
