sim.env.data: Simulates cases and controls

In kwesterman/ESPRESSO.GxE.RV: Power analysis and sample size calculation for a multi-variant gene-environment interaction model

Simulates cases and controls

Description

Generates data for a binary, quantitative-normal, or quantitative-uniform environmental determinant.

Usage

sim.env.data(
  num.obs = NULL,
  env.model = NULL,
  env.prev = NULL,
  env.mean = NULL,
  env.sd = NULL,
  env.low.lim = NULL,
  env.up.lim = NULL
)

Arguments

num.obs	number of observations to simulate.
env.model	model of the exposure: binary=0, quantitative-normal=1, quantitative-uniform=2.
env.prev	prevalence of the environmental exposure.
env.mean	statisitical man under quantitative-normal model.
env.sd	standard deviation under quantitative-normal model.
env.low.lim	lower limit under quantitative-uniform model.
env.up.lim	upper limit under quantitative-uniform model.

Value

a vector of continuous or binary values.
