make_x_bivariate: Simulate X variables

Description

Simulates independent variables.

Usage

make_x_bivariate(n = 5, mu = 1, cor = 0.25, var = c(1, 1))
make_x_uniform(n = 5, var = 1)
make_x_normal(n = 5, mu = 0, var = 1)
make_x(
  n = 5,
  mu = 0,
  var = 1,
  cor = 0,
  method = c("uniform", "normal", "bivnormal")
)

Value

A data.frame of the simulated independent variables.

Arguments

n

the number of values to simulate.

mu

the sample average.

cor

correlation between bivariate normal

var

the sample variance. The sqrt(var) is passed to rnorm() and rlnorm() for normal and laplace distributions. sqrt(var / 2) is used for laplace() .

method

must be one of "uniform" (default), "normal", or "bivnormal" (bivariate normal).

Examples

make_x(10, mu = c(0.5, 1.2), var = c(1, 0.5))
