|
X1 |
count of homozygotes of the first kind [<-> genotype AA] |
X2 |
count of heterozygotes [<-> genotype AB] |
X3 |
count of homozygotes of the second kind [<-> genotype BB] |
alpha |
1 - confidence level |
SW |
width of the search grid for determining an interval covering the parameter point at which the conditional distribution function takes value α and 1-α, respectively |
TOL |
numerical tolerance to the deviation between the computed confidence limits and their exact values |
ITMAX |
maximum number of interval-halving steps |
The program exploits the structure of the family of all genotype distributions, which is 2-parameter exponential with \log(REH) as one of these parameters.
