Conditional and Unconditional Tests (and Sample Size) Based on Multiple Comparisons for Stratified 2 × 2 Tables

Table 4

Sample sizes by stratum () and global () obtained by various methods for the data of Jung’s example [10] under Model 2. Each asymptotic method is placed immediately below the exact method from which it proceeds.

Model	Test	Procedure	Stratum
			1	2	3
Conditional	Exact	Jung	10, 10	10, 10	11, 11	62
	Asymptotic	without cc	8, 8	8, 8	9, 9	50
		with cc	11, 11	11, 11	12, 12	68
Unconditional	Exact	MC (Barnard’s order)	12, 12	12, 12	13, 13	74
			10, 11	11, 12	12, 13	69
			1, 2	11, 12	12, 13	51
	Asymptotic	MC ( with cc)	11, 11	12, 12	12, 12	70
			10, 11	11, 12	12, 13	69
			1, 2	11, 12	12, 13	51

Note: : of Mantel-Haenszel; MC = multiple comparisons method; of Model 2.
