The power function of the test for the difference between two proportions in a 2 × 2 table. By P. B. PATNAEK.
I am indebted to Mr R. L. Turner for pointing out some errors in formulae on pp. 1723 of this paper:
(a) p. 172, the expressions for h1 and h2 should read
,
(b) p. 173, in equation (25) for
read (1+
(1p1)p2), an expression which may also be written as
q1 + q2
It seems probable that these errors crept in at some stage in the copying of my MS. as the numerical values for the second approximation to the power function given in the examples in Table 3 have been found to be correct.
