Log-Likelihood value of systemfit object
This method calculates the log-likelihood value
of a fitted object returned by
an object of class
If this argument is set to
currently not used.
The residual covariance matrix that is used for calculating the log-likelihood value is calculated based on the actually obtained (final) residuals (not correcting for degrees of freedom). In case of systems of equations with unequal numbers of observations, the calculation of the residual covariance matrix is only based on the residuals/observations that are available in all equations.
A numeric scalar (the log-likelihood value) with 2 attributes:
nobs (total number of observations in all equations) and
df (number of free parameters, i.e. coefficients
+ elements of the residual covariance matrix).
