simulation: Repeats the data generation process in a simulation scheme

In BinNor: Simultaneous Generation of Multivariate Binary and Normal Variates

Description

Simulates many versions of mixed data, and reports averaged proportion, mean, variance and correlation estimates across replications.

Usage

simulation(seed = NULL, nsim, no.rows, no.bin, no.nor, 
	mean.vec.nor = NULL, var.nor = NULL, prop.vec.bin = NULL, 
	corr.vec = NULL, corr.mat = NULL, continue.with.warning = TRUE)

Arguments

seed	A seed value for the random number generator. Seed value will be randomly generated unless specified.
nsim	Number of simulation runs.
no.rows	Number of rows.
no.bin	Number of binary variables
no.nor	Number of normal variables
prop.vec.bin	Probability vector for binary variables
mean.vec.nor	Vector of means for normal variables
var.nor	Vector of variances for normal variables
corr.vec	Vector of elements below the diagonal of correlation matrix ordered columnwise
corr.mat	Specified correlation matrix
continue.with.warning	TRUE to proceed with the nearest positive definite Σ^*. FALSE to terminate program execution if Σ^* is not positive definite

Examples

simulation(nsim=10, no.rows=100, no.bin=2, no.nor=2, 
		mean.vec.nor=c(3,1), var.nor=c(4,2), prop.vec.bin=c(0.4,0.7),
		corr.vec=c(0.16,0.04,0.38,0.14,0.47,0.68), corr.mat=NULL)
