R: Log likelihood ratio test on two fitted models
Log likelihood ratio test on two fitted models
Description
Performs a log likelihood ratio test on two fitted
depmix models.
Usage
llratio(basemodel, constrainedmodel, ...)
Arguments
basemodel |
Fitted model with a logLik method.
|
constrainedmodel |
Fitted model with a logLik method.
|
... |
Not currently used.
|
Details
See the fit help page for an example.
Value
llratio returns an object of class llratio which has slots:
value |
: Minus twice the loglikelihood difference.
|
df |
: The degrees of freedom, ie the difference in number of freely
estimated paraemters between the models.
|
The print method shows the value, the degrees of freedom and the
corresponding p-value under the chisquared distribution.
