The following definitions are used in the table:

rxy	=	Validity coefficient
Zxi	=	Cutoff point (score) on the predictor in standard-score units
φI	=	Selection ratio
yi	=	mean criterion score (in standard-score units) of all cases above cutoff
λI	=	Ordinate of normal distribution at Zxi

And the table is based upon the following equation:

Note: The use of the table may differ slightly in the case where r_xy is really a multiple regression ...
