# logLik.pmtree

From model4you v0.9-5
by Heidi Seibold

##### Extract log-Likelihood

Extract sum of log-Likelihood contributions of all terminal nodes. By default the degrees of freedom from the models are used but optionally degrees of freedom for splits can be incorporated.

##### Usage

```
# S3 method for pmtree
logLik(object, dfsplit = 0, newdata = NULL,
weights = NULL, perm = NULL, ...)
```

##### Arguments

- object
pmtree object.

- dfsplit
degrees of freedom per selected split.

- newdata
an optional new data frame for which to compute the sum of objective functions.

- weights
weights.

- perm
the number of permutations performed (see

`varimp`

).- ...
ignored.

##### Value

Returns an object of class `logLik`

.

##### See Also

`objfun.pmtree`

for the sum of contributions to the
objective function (not the same when partitioning linear models `lm`

)
