Different experimental models have been used or suggested for different purposes, including graphic analysis only (Zeeman, Hall, Harrison, Marriage, & Shapland, 1976), behavior surface to control surface mapping rules (Benham & Kozak, 1976;Gilmore, 1981;Guastello, 1981a;Jiobu & Lundgren, 1978;Oliva, Peters, & Murthy, 1981;Sheridan, 1980;Smith, 1980), qualitative classification of time series patterns (Guastello, 1981b), stationary regression models (Cobb, 1978(Cobb, , 1981a(Cobb, , 1981b. The latter group is of particular interest since it is the closest to what will be discussed.…”
