genCorrelatedData: Generates a data frame (x1,x2,y) with user-specified correlation between x1 and x2

Description

Generates a data frame (x1,x2,y) with user-specified correlation between x1 and x2

Usage

genCorrelatedData(N = 100, means = c(50, 50),
    sds = c(10, 10), rho = 0, stde = 1,
    beta = c(0, 0.2, 0.2, 0))

Arguments

N

Number of cases desired

means

2-vector of means for x1 and x2

sds

2-vector of standard deviations for x1 and x2

rho

Correlation coefficient for x1 and x2

stde

standard deviation of the error term in the data generating equation

beta

beta vector of at most 4 coefficients for intercept, slopes, and interaction
