XLSTAT - Cochran-Armitage Trend Test
Principles of the Cochran-Armitage trend test
The Cochran Armitage trend is used to test if a series of proportions, possibly computed from a contingency table, can be considered as varying linearly with an ordinal or continuous variable.
It can be a one- or two-sided test.
