st6 {corTest}

Test Differential Correlation Using st6 Method

Description

Compute p-value for the equal correlation test with another way to combine Spearman corrleaion and percentage bend correlation based on a multiple logistic regression model corresponding to two independent groups

Usage

st6(x1, z1, x0, z0)

Arguments

x1

a numeric vector

z1

a numeric vector with same length as x1

x0

a numeric vector

z0

a numeric vector with same length as x0

Value

A list with 3 elements:

u

the vector of Fisher score.

pval

p-value of test for testing if correlation between x1 and z1 is the same as that between x0 and z0

cov_u

covariance matrix for u.

Examples

x1 = ghdist(n = 100, g = 0.2, h = 0.2)
x0 = ghdist(n = 100, g = 0.2, h = 0.2)
z1 = x1 + ghdist(n = 100, g = 0.2, h = 0.2)
z0 = x0 + ghdist(n = 100, g = 0.2, h = 0.2)
res = st6(x1, z1, x0, z0)
print(res)
