predict.glmmPQL {MASS} | R Documentation |
Obtains predictions from a fitted generalized linear model with random effects.
## S3 method for class 'glmmPQL' predict(object, newdata = NULL, type = c("link", "response"), level, na.action = na.pass, ...)
object |
a fitted object of class inheriting from |
newdata |
optionally, a data frame in which to look for variables with which to predict. |
type |
the type of prediction required. The default is on the
scale of the linear predictors; the alternative |
level |
an optional integer vector giving the level(s) of grouping to be used in obtaining the predictions. Level values increase from outermost to innermost grouping, with level zero corresponding to the population predictions. Defaults to the highest or innermost level of grouping. |
na.action |
function determining what should be done with missing
values in |
... |
further arguments passed to or from other methods. |
If level
is a single integer, a vector otherwise a data frame.
