funsZcell.nnct.pval | R Documentation |
Four functions: Zcell.nnct.2s
, Zcell.nnct.rs
, Zcell.nnct.ls
and Zcell.nnct.pval
.
These functions yield a contingency table (i.e., a matrix) of the p-values for the cell-specific Z
test statistics for the NNCT and take the cell-specific Z test statistics in matrix form as their argument.
Zcell.nnct.pval
yields an array of size k \times k \times 3 where 1st entry of the array is the matrix of p-values for the
two-sided alternative, 2nd entry of the array is the matrix of p-values for the left-sided alternative
and 3rd entry of the array is the matrix of p-values for the right-sided alternative.
And each of Zcell.nnct.2s
, Zcell.nnct.rs
and Zcell.nnct.ls
yield a k \times k matrix of p-values
for the two-sided, right-sided and left-sided alternative, respectively.
The functions Zcell.nnct.2s
, Zcell.nnct.rs
and Zcell.nnct.ls
are equivalent to
Zcell.nnct(...,alt)$p.val
where alt="two-sided"
, "greater"
and "less"
, respectively, with the appropriate
arguments for the function Zcell.nnct
(see the examples below).
