The predictions at level 0 correspond to population predictions (based only on the fixed effects estimates). The predictions at level 1 are obtained by adding the best linear predictions of the random effects to the predictions at level 0.
Usage
## S3 method for class 'lqmm':
predict(object, level = 0, ...)
Arguments
object
an lqmm object.
level
an optional integer vector giving the level of grouping to be used in obtaining the predictions. Level zero corresponds to the population predictions.
...
not used.
Value
a matrix of predictions.
