ANOVA power dialog for a crossover design
This GUI (separate window) may be used to study power and sample-size
problems for a popular crossover design. The factors sequence, period,
and treatment are arranged in a Latin square, and SUBJECT is nested in
sequence.
Click or drag on the bar graphs to adjust values; or
enter values in the text areas and hit RETURN. (Power
values are not adjustable.) You can change the scales for
the bar graphs by dragging from any point along the scale to
its desired new position -- provided that this would not
cause a bar to go out-of-bounds.
