In mixl: Simulated Maximum Likelihood Estimation of Mixed Logit Models for Large Datasets

Extract the availabilites matrix from the dataset, using column indicies

Description

Extract the availabilites matrix from the dataset, using column indicies

Usage

av_matrix(data, av_cols)

Arguments

data	The dataset used in the model
av_cols	A vector of the the column indicies of the availabilities for each alternative

Value

Matrix of availabilities for alternatives and the number of choice observations

Examples

data("Train", package="mlogit")
Train$ID <- Train$id
Train$CHOICE <- as.numeric(Train$choice)
Train$avail_A <- sample(2, replace=TRUE, size=nrow(Train))-1
Train$avail_B <- sample(2, replace=TRUE, size=nrow(Train))-1
av_matrix(Train, c('avail_A', 'avail_B'))
