ordinal.data: A function for ordinal categorical response data generation.

Description

ordinal.data generates ordered category response data (with p covariates and a treatment variable).

Usage

ordinal.data(n = 400, p = 10, R = 11, delta = 1, s = "nonlinear")

Arguments

n

sample size.

p

dimension of covariates.

R

number of response levels in y

delta

magnitude of "main" effect (i.e., "nuisance" effect) of the covariates; a large delta means a larger "nuisance" variance.

s

type of the treatment-by-covariates interation effect ("linear" or "nonlinear")

Value

y

a n-by-1 vector of treatment outcomes.

A

a n-by-1 vector of treatment indicators.

X

a n-by-p matrix of pretreatment covariates.

SNR

the "signal" (interaction effect) to "nuisance" (main effect) variance ratio (SNR) in the canonical parameter function.

true.beta

the true single-index coefficient vector.

delta

magnitude of "main" effect.

s

type of the treatment-by-covariates interation effect.
