TITLE:  mix14
	
	4-class model representing two 2-class latent variables
	proposed by Goodman (1974), pages 229-231.
	See also Bartholomew (1987), pages 23-25.

	Coleman's panel data on student attitudes (n=3398).
	Two points in time, 1 and 2. Measures:
	Member = self-perceived membership in the leading crowd? 
		(Yes=1, No=0)
	Attitud = does membership involve sometimes going against
		principles? (Yes=0, No=1)
