crossmatchdist:
The Exact Null Distribution Of The Cross-match Statistic Under The Null
Description
The exact null distribution of the number of crossmatches for bigN>=4 cases,
n>=2 from one type and N-n>=2 from another type.
Usage
crossmatchdist(bigN, n)
Arguments
bigN
The total number of observations
n
The number of cases from one type
Value
dist
A matrix with rows a0, a1, a2, Pr(A1=a1) and Pr(A1<=a1)< code="">.
Details
bigN is even. Let a1 be the number of cross-matches pairs. Then a2=(n-a1)/2 and
a0=bigN/2-(n+a1)/2 are the number of pairs both of one type and the other type
respectively.
