compose_identical: Compose identical choice sets

In nikitagusarov/dcesimulatr: Discrete Choice Experiment Simulator

Compose identical choice sets

Description

This is an internal function which creates identical choice sets configurations for give experimental design. The function simplifies the size adjustment of Z depending on the population size of X.

Usage

compose_identical(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_identical(edesign, size = 2)
