def crossed_data():
    '''
    Random effects:
    10 subjects, 12 items, 5 sites
    Subjects crossed with items, nested in sites
    Items crossed with sites

    Fixed effects:
    A continuous predictor, a numeric dummy, and a three-level category
    (levels a,b,c)

    Structure:
    Subjects nested in dummy (e.g., gender), crossed with threecats
    Items crossed with dummy, nested in threecats
    Sites partially crossed with dummy (4/5 see a single dummy, 1/5 sees both
    dummies)
    Sites crossed with threecats
