Using SPSS MANOVA to fit a within subjects ANCOVA with a constant covariate

It is assumed in this example we have a covariate with identical responses within subject (x1, x2) and a repeated measures factor of 2 levels (y1, y2). This approach effectively follows Winer(1971), p.803 and omits any terms the covariate by factor interaction from the within subjects portion of the ANCOVA.

In general an identical covariate column may be generated using the COMPUTE statement in SPSS.

COMPUTE x2 = X1.
