Calculates any one parameter of the binomial
distribution given values for the others.
Arguments
WHICH --> Integer indicating which of the next four argument
values is to be calculated from the others.
Legal range: 1..4
iwhich = 1 : Calculate P and Q from S,XN,PR and OMPR
iwhich = 2 : Calculate S from P,Q,XN,PR and OMPR
iwhich = 3 : Calculate XN from P,Q,S,PR and OMPR
iwhich = 4 : Calculate PR and OMPR from P,Q,S and XN
P <--> The cumulation from 0 to S of the binomial distribution.
(Probablility of S or fewer successes in XN trials each
with probability of success PR.)
Input range: [0,1].
Q <--> 1-P.
Input range: [0, 1].
P + Q = 1.0.
S <--> The number of successes observed.
Input range: [0, XN]
Search range: [0, XN]
XN <--> The number of binomial trials.
Input range: (0, +infinity).
Search range: [1E-100, 1E100]
PR <--> The probability of success in each binomial trial.
Input range: [0,1].
Search range: [0,1]
OMPR <--> 1-PR
Input range: [0,1].
Search range: [0,1]
PR + OMPR = 1.0
STATUS <-- 0 if calculation completed correctly
-I if input parameter number I is out of range
1 if answer appears to be lower than lowest
search bound
2 if answer appears to be higher than greatest
search bound
3 if P + Q .ne. 1
4 if PR + OMPR .ne. 1
BOUND <-- Undefined if STATUS is 0
Bound exceeded by parameter number I if STATUS
is negative.
Lower search bound if STATUS is 1.
Upper search bound if STATUS is 2.
