Usage

Arguments

model	The output of a model estimated model using the logitr() function. Include if you want to compare true choices from actual observations (e.g. hold outs) to the predicted choices.
alts	A data frame of a set of alternatives for which to predict choices. Each row is an alternative and each column an attribute corresponding to parameter names in the estimated model.
altID	The name of the column that identifies each alternative in each set of alternatives.
obsID	The name of the column that identifies each set of alternatives. Required if predicting results for more than one set of alternatives. Defaults to NULL (for a single set of alternatives).
