RespondMNL {idefix}

Response generation

Description

Function to generate random responses given parameter values and a design matrix, assuming a MNL model.

Usage

RespondMNL(par, des, n.alts, bin = TRUE)

Arguments

par

Numeric vector containing parameter values.

des

A design matrix in which each row is a profile. If alternative specific constants are present, those should be included as the first column(s) of the design. Can be generated with Modfed or CEA.

n.alts

Numeric value indicating the number of alternatives per choice set.

bin

A logical value indicating whether the returned value should be a binary vector or a discrete value which denotes the chosen alternative.

Value

Numeric vector indicating the chosen alternatives.

Examples

# design: 3 dummy coded attributes, each 3 levels. There are 8 choice sets.
des <- example_design
set.seed(123)
true_par <- rnorm(6)
RespondMNL(par = true_par, des = des, n.alts = 2)
