Table 7 Critical values of g1and g2for Fisher’s cumulant test

The g1distribution may be considered as symmetrical with respect to 0;

the g2distribution has to be considered as asymmetrical.

The columns a denote the lower boundaries or left-sided critical values.

The columns b denote the upper boundaries or right-sided critical values.

r = 0

Table 18 Critical values of r for the sign test for paired observations

N is the total number of equally probable dichotomous events, r

the smaller of the number of events of either kind If r ≤ rN;α

then there are too few events of one kind at the 1 − α confidence level.

For large values of N, r is approximately distributed as z.
