MAMBAC (mean above minus mean below a cut; Meehl & Yonce, 1994), MAXCOV-HITMAX (Meehl, 1995; Meehl & Yonce, 1996) and MAXEIG (Waller & Meehl, 1998) are three popular procedures. Other taxometric procedures such as L-mode (Waller & Meehl, 1998) and MAXSLOPE (Grove, 2004) are somewhat less popular. As the general structures of the procedures are similar, MAXCOV is explained in more detail, and details concerning MAMBAC and MAXEIG are given in the online Supplementary material.
