(y1,y2, y3, y4), unfortunately suffering from some successive dropouts (i.e.
the sample sizes varies for y1, y2, y3, and y4). For every y, two other
variables (covariates) were also measured: x & z, and both do presumably
exert an effect on y. At some cutoffs, x can also be trichotomized into 3
ordinal levels constituting a presumed factor (fx) influencing the level of
y at all of the different measurings (1-4). x and fx are rather stable
arcoss the 4 measurements whereas z is not. H0 is that x and fx are not
influencing the level of y (i.e. explaining any variance of y) irrespecti...
