Correction Formulas for Correlations Restricted by Selection on an Unmeasured Variable.
Alexander, Ralph A.
Journal of Educational Measurement, v27 n2 p187-89 Sum 1990
This note shows that the formula suggested by N. D. Bryant and S. Gokhale (1972) for correcting indirectly restricted correlations when no information is available on the third (directly restricted) variable is accurate only in one special instance. A more general correction formula is illustrated. (SLD)
