Extract various types of predictions from CountsEPPM regression models.
1 2 3 4 5 6 |
object |
fitted model object of class "CountsEPPM". |
newdata |
optionally, a data frame in which to look for variables with which to predict. If omitted, the original observations are used. |
type |
character indicating type of predictions: fitted means of responses ("response"), linear predictors ("linear.predictor.mean", "linear.predictor.scale.factor"), fitted value of mean ("mean"), fitted value of scale-factor ("scale.factor"), fitted value of variance ("variance"), fitted probability distribution ("distribution"), parameters of fitted distributions ("distribution.parameters") |
na.action |
function determining what to do with missing values in newdata. The default is to predict NA. |
... |
some methods for this generic function require additional arguments. |
A vector or list of the predicted values from the fitted model object.
