gof function

Extract TRIM goodness-of-fit information.

trim computes three goodness-of-fit measures:

• Chi-squared
• Likelihood ratio
• Akaike Information content

gof(x)

## S3 method for class 'trim'
gof(x)

Arguments

• x: an object of class trim (as returned by trim)

Returns

a list of type "trim.gof", containing elements chi2, LR

and AIC, for Chi-squared, Likelihoof Ratio and Akaike informatiuon content, respectively.

Examples

data(skylark)
z <- trim(count ~ site + time, data=skylark, model=2)
# prettyprint GOF information
gof(z)

# get individual elements, e.g. p-value
L <- gof(z)
LR_p <- L$LR$p # get p-value for likelihood ratio
