varRCA {psychometric} | R Documentation |
Computes the estimate of the variance in the corrected correlation coefficient.
varRCA(x, aprox = FALSE)
x |
A matrix or data.frame with columns Rxy, n and artifacts (Rxx, Ryy, u):
see EnterMeta |
aprox |
Logical test to determine if the approximate or exact var e is used |
Variance in Rho is computed as: VarResT
/ CAFFA
^2
This is used to construct credibility intervals for rho CredIntRho
A numeric value representing the variance in the population correlation coefficient
