Contours of equal values at significance levels α = 0.01 (solid line), 0.001
(dashed line), 0.0001 (dotted line), and 0.00001 (dotted-dashed line): (a) combined
Z
,
(b) Fisher combined
p
, and (c) Venn diagram. (d) All three rules (α = 0.001).
In Fig. 1(a); the rule for combined
Z
(i.e.
-
) with equal weighting is
shown. Contours for this rule are straight lines in this two-dimensional
case, and are more generally hyperplanes. Equal weighting implies a slope
of
−
1; use of other weights just changes the angle of the line. Figure 1(b)
