In Karena6688/qcSSMD: calcuate SSMD for quality control

Description

A function to calculate UMVUE estimate of SSMD

Usage

ssmdEstCore.homoVAR.fn(m1, m2, s1, s2, n1, n2, approx = F, method = "UMVUE")

Arguments

m1	sample mean of values in the first group (i.e., the reference group)
m2	sample mean of values in the second group
s1	sample standard deviation of values in the first group (i.e., the reference group)
s2	sample standard deviation of values in the second group
n1	sample size in the first group (i.e., the reference group)
n2	sample size in the second group
approx	approx=TRUE, indicating the use of approximation for the coefficient in the UMVUE estimate of SSMD
method	specify the method for estimating SSMD. It must be

Value

a vector
