game.pred {mvglmmRank}

Predict outcomes of games.

Description

After fitting a model with mvglmmRank, game.pred uses that model to predict outcomes of future matchups.

Usage

game.pred(res, home, away, neutral.site = FALSE)

Arguments

res

an object of class mvglmmRank

home

a character string for the home team (use quotation marks!)

away

a character string for the away team (use quotation marks!)

neutral.site

logical. If TRUE, uses the neutral site mean score, assuming some of the games in the training data occured at neutral sites.

Value

Prints predicted scores and/or predicted probability of a home team win, depending on the type of model specified by res.
