A Comparison of Significance‐Testing Procedures for Parent–Child Correlations Computed from Family Data

Abstract: Procedures are studied for testing the statistical significance of a parent–child correlation coefficient, ρab, computed from data having a variable number of siblings per family. It is demonstrated that a simple and reasonably powerful test is obtained by comparing the pairwise estimator rp to the value of its large sample standard error and referring to tables of the standard normal distribution. This test procedure compares favourably to the likelihood ratio test in studies having as few as 25 families, especially for low values of ρab.
