genXdata {probs}

Generate continuous model matrix data

Description

This function generates correlated normal data to serve as a model matrix in a regression model.

Usage

genXdata(
  n,
  nvar = 1,
  mu = rep(0, nvar),
  Sigma = diag(length(mu)),
  varnames = paste("x", 1:length(mu), sep = ""),
  roundto = NULL
)

Arguments

n

how many rows

nvar

how many columns

mu

the mean of the multivariate normal distribution

Sigma

the variance-covariance matrix of the normal distribution

varnames

how you would like the variables to be named in the result

roundto

number of places to round the generated values

Details

This function generates correlated normal data to serve as a model matrix in a regression model.

Value
