Calculate Spearman's rank correlation with its confidence intervals by SAS method

Description

Calculate Spearman's rank correlation with its confidence intervals by the same method as SAS. Since fmsb-0.7.3, missing values are excluded pairwisely before calculation.

Usage

 spearman.ci.sas(x, y, adj.bias=TRUE, conf.level=0.95) 

Arguments

x	A numeric vector.
y	A numeric vector.
adj.bias	Logical. If TRUE, adjustment for bias is taken. Default TRUE.
conf.level	Probability for confidence intervals. Default is 0.95.

Value

rho	Calculated point estimate of Spearman's rank correlation coefficient.
rho.ll	The lower limit of given confidence intervals.
rho.ul	The upper limit of given confidence intervals.
