convert_r: Convert r for NORTA

Description

Given a target r-value, returns the correlation you need to induce in a bivariate normal distribution to have the target correlation after converting distributions.

Usage

convert_r(
  target_r = 0,
  dist1 = "norm",
  dist2 = "norm",
  params1 = list(),
  params2 = list(),
  tol = 0.01
)

Value

r-value to induce in the bivariate normal variables

Arguments

target_r

The target correlation

dist1

The target distribution function for variable 1 (e.g., norm, binom, gamma, truncnorm)

dist2

The target distribution function for variable 2

params1

Arguments to pass to the functions for distribution 1

params2

Arguments to pass to the functions for distribution 2

tol

Tolerance for optimise function

Details

See Distributions for distributions and their various arguments to specify in params1 and params2.

Examples

convert_r(target_r = 0.5, 
          dist1 = "norm", 
          dist2 = "binom", 
          params1 = list(mean = 100, sd = 10),
          params2 = list(size = 1, prob = 0.5))
