av_matrix function

Extract the availabilites matrix from the dataset, using column indicies

Extract the availabilites matrix from the dataset, using column indicies

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

Returns

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'))
