Extract standard model-fit quantities

These methods expose drmTMB fits to standard base-R model summary and comparison helpers.

Usage

# S3 method for class 'drmTMB'
nobs(object, ...)

# S3 method for class 'drmTMB'
df.residual(object, ...)

# S3 method for class 'drmTMB'
deviance(object, ...)

Arguments

object

A drmTMB fit.

...

Reserved for future extractor options.

Value

Numeric scalar.

Details

nobs() returns the number of fitted rows after complete-case filtering. df.residual() returns nobs - df, where df is the number of optimized top-level parameters recorded in logLik(). deviance() returns -2 * logLik; for these likelihood-based distributional models this is an absolute negative twice log-likelihood value, not a saturated-model GLM deviance.
