Calculate variance-covariance matrix for a fitted model object — vcov.s4t_cjs_ml • space4time

Calculate variance-covariance matrix for a s4t_cjs_ml model object.

Usage

# S3 method for class 's4t_cjs_ml'
vcov(object, ...)

Arguments

object: a s4t_cjs_ml object fitted using fit_s4t_cjs_ml().
...: Other arguments. Not used (needed for generic consistency)

Value

The variance-covariance matrix of coefficients from a fitted s4t_cjs_ml object

Examples

if (FALSE) { # \dontrun{
sim.dat <- sim_simple_s4t_ch(N = 2000)
m1 <- fit_s4t_cjs_ml(p_formula = ~ t,
                     theta_formula = ~ a1 * a2 * s * j,
                     ageclass_formula = ~ FL,
                     fixed_age = TRUE,
                     s4t_ch = sim.dat$s4t_ch)

vcov(m1)
} # }
