"predict"(object, newdata = NULL, type = c("utility", "probability"),
...)NULL, the original data is used.
newdata = NULL and type = utility, a vector containing utility
values of choosing Yes under bid values is returned. When newdata = NULL
and type = probability, a vector containing probabilities of choosing Yes
is returned. When a new data is assigned to newdata, a vector containing
utility values of choosing Yes (type = utility) or probability of
choosing Yes (type = probability) under the new data is returned.
predict() for S3 object "sbchoice" calculates predicted values
according to the fitted model that is included in object. The values are
predicted with the original data used for fitting the model if newdata = NULL,
otherwise with a new data assigned to newdata.The current function does not estimate standard errors of predicted values.
