See Also

• fit() Fit a model

• mod_pois(), mod_binom(), mod_norm() Specify a model

• set_seeds() Reset random seeds

• Functions such as set_prior(), set_disp() and set_var_age() unfit models as side effects.

Examples

## create a model, which starts out unfitted
mod <- mod_pois(injuries ~ age + sex + year,
                data = nzl_injuries,
                exposure = popn)
is_fitted(mod)

## calling 'fit' produces a fitted version
mod <- fit(mod)
is_fitted(mod)

## calling 'unfit' resets the model
mod <- unfit(mod)
is_fitted(mod)
