Specializes the `logLik`

function for the market models
of the package estimated with full information minimum likelihood. It
returns `NULL`

for the equilibrium model estimated with two stage
least squares (`method = "2SLS"`

).

## Value

A `logLik`

object.

## Examples

```
# \donttest{
# estimate a model using the houses dataset
fit <- diseq_deterministic_adjustment(
HS | RM | ID | TREND ~
RM + TREND + W + CSHS + L1RM + L2RM + MONTH |
RM + TREND + W + L1RM + MA6DSF + MA3DHF + MONTH,
fair_houses(),
correlated_shocks = FALSE,
estimation_options = list(control = list(maxit = 1e+6))
)
# get the log likelihood object
logLik(fit)
#> 'log Lik.' -862.3327 (df=39)
# }
