Uses the edge probabilities from G
to calculate the log likelihood of the model.
1 | LogLike.APFA(G, dat, complete.cases=TRUE)
|
G |
a fitted APFA |
dat |
a data frame that contains the same variables that G is based on. |
complete.cases |
a Boolean that determines whether incomplete cases are included in the calculations (see Details). |
An observation in the data may not be in the sample space of the APFA, i.e. there may not a root-to-sink path in the APFA generating
the observation. However, there will be a partial path, that is, generating the initial part of the observation.
If complete.cases
is true, such observations are excluded from the calculations, otherwise contributions from the partial path are included.
See the reference below for the per-symbol log-likelihood.
Returns the log-likelihood and the per-symbol log-likelihood.
