    hello,

    i have problems coding the syntax for an anova with two factors,
    one between- and one within-subjects-factor (see syntax below).
    accordingly, there are 4 combinations of levels:
    wth_level1-btw_level1, wth_level2-btw_level1, wth_level1-
    btw_level2 and wth_level2-btw_level2.
    i am interested in the contrast of the two middle combinations
    (wth_level2-btw_level1, wth_level1-btw_level2) vs. the first one
    (wth_level1-btw_level1).
    could anybody help me writing the syntax command for this
    contrast? this would be great!
    thanks in advance! best, dht

    GLM wth_stufe1 wth_stufe2 BY btw
    /WSFACTOR=wth_faktor 2 Polynomial
    /METHOD=SSTYPE(3)
    /CRITERIA=ALPHA(.05)
    /WSDESIGN= wth_faktor
    /DESIGN=btw.
