compose_distinct: Compose random choice sets

In nikitagusarov/dcesimulatr: Discrete Choice Experiment Simulator

Compose random choice sets

Description

This is an internal function which creates distinct choice sets configurations for give experimental design. The function simplifies the size adjustment of Z depending on the population size of X. Each individuals faces a personalised Z version.

Usage

compose_distinct(experimental_design, n = NULL, size)

Arguments

experimental_design	An 'experimental_design' object.
n	Number of different choice situations per individual. Is NULL by default, ensuring that the function will retreive the n value from the 'experimental_design'.
size	Population size for Z to be adjusted to.

Value

data.frame Z dataset

Examples

# Create alternatives
alt1 <- alternative$new()
alt1$add_attributes(Quality = runif(min = 0, max = 1), Price = rnorm(mean = 5))
alt2 <- alternative$new()
alt2$add_attributes(Size = runif(min = 0, max = 1), Price = rnorm(mean = 6))

# Regroup alternatives into design
edesign <- experimental_design$new(alternatives = list(alt1, alt2), n = 4)

# Compose
Z <- compose_distinct(edesign, size = 2)
