Compute likelihood ratio tests of two fitted model objects — anova.s4t_ageclass

Compute analysis of variance table.

Usage

# S3 method for class 's4t_ageclass_model'
anova(object, ...)

Arguments

object: object of class s4t_ageclass_model created using fit_ageclass()
...: object of class s4t_ageclass_model (for generic consistency)

Value

Returns a data frame with the difference in degrees of freedom, test statistic (chi-squared), and p-value for the likelihood ratio tests between the full (assumed to be the model with the largest degrees of freedom) and reduced model.

Examples

if (FALSE) { # \dontrun{
sim.dat <- sim_simple_s4t_ch(N = 2000)
m1 <- fit_ageclass(ageclass_formula = ~ FL + obs_time,
                   s4t_ch = sim.dat$s4t_ch)
m2 <- fit_ageclass(ageclass_formula = ~ FL + I(FL^2) + obs_time,
                   s4t_ch = sim.dat$s4t_ch)
anova(m1, m2)
} # }
