In jknowles/datasynthR: Generate synthetic data with known properties, on demand.

Description

Allow user to draw from a random chi-square distribution correlated with a user specified vector

Usage

rchisqcor(x, rho, na.rm = FALSE)

Arguments

x	variable to draw from
rho	correlation coefficient between x and result of function

Examples

x <- rnorm(1000, 1, 1)
y <- rchisqcor(x, 0.2)
cor(x,y) # very close to 0.2
mean(y) 
sd(y)
