McGraw, Kenneth O.; And Others
Journal of Consulting and Clinical Psychology, v62 n5 p960-64 Oct 1994
Suggest practical procedure for estimating number of subjects that need to be screened to obtain sample of fixed size that meets multiple correlated criteria. Procedure described is based on fact that least-squares regression provides good quadratic fit for Monte Carlo estimates of multivariate probabilities when they are plotted as function of mean pairwise correlations for criterion variables.
