sim_variable: Simulate a single variable using the inversion method

In rje42/causl: Methods for Specifying, Simulating from and Fitting Causal Models

Simulate a single variable using the inversion method

Description

Each entry formulas, family, pars, link is a list with two entries, the first referring to the variable being simulated and the second to the pair-copulas being used.

If the quantile is smaller than tol or bigger than 1 - tol the associated value is moved to tol and 1 - tol respectively.

Usage

sim_variable(
  n,
  formulas,
  family,
  pars,
  link,
  dat,
  quantiles,
  tol = 10 * .Machine$double.eps
)

Arguments

n	sample size
formulas	list consisting of a formula for the output variables and a list of formulae for the pair-copula
family	list containing family variable
pars	list with two entries, first a list of parameters for response, and second a further list of parameters for pair-copula
link	list of same form as family
dat	data frame of current variables
quantiles	data frame of quantiles
tol	tolerance for quantile closeness to 0 or 1

Value

The data frame dat with an additional column given by the left-hand side of formula[[1]].
