Predicts the probability of counts given a family object of class
"familyWALScount". Only works for count data models.
predictCounts(x, ...)# S3 method for familyWALScount
predictCounts(x, yUnique, rowNames, eta, ...)
Returns a matrix of dimension length(eta) times
length{yUnique} with the predicted probabilities of the counts given
in yUnique for every observation in eta.
object of class "familyWALScount".
Further parameters passed to density() function in
family.
vector. The counts (larger or equal to zero) which to predict probabilities for.
vector. The names of the observations.
vector. The fitted linear link \(\hat{\eta}\) of the model.
"familyWALScount" objects are used in the fitting methods
walsNB, walsNBmatrix,
walsGLM or walsGLMmatrix. For the
latter two, only the family poissonWALS is currently
supported.
predictCounts() is not available for objects of any class except for
"familyWALScount".
The predictCounts.familyWALScount() method is a modified version of the
predict.hurdle() method from the countreg package
version 0.2-1 (2023-06-13) countreg,countreghurdleWALS using the argument
type = "prob".
