gendata_MLR: Generate Simulated Data with Multinomial Logistic Regression Model

Description

This function generates the response variables y given optional supplied X using a multinomial logistic regression model.

Usage

gendata_MLR(n, p, NC = 3, nu = 2, w = 1, X = NULL, betas = NULL)

Value

A list contains input matrix X, response variables y, and regression coefficients deltas.

Arguments

n

Number of observations.

p

Number of features.

NC

Number of classes for response variables.

nu, w

If betas is not supplied (default), the regression coefficients are generated with t prior with df = nu, scale = sqrt(w); will be ignored if betas is supplied.

X

The design matrix; will be generated from standard normal distribution if not supplied.

betas

User supplied regression coefficients.
