Calculates any one parameter of the binomial
distribution given values for the others.
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]

This will produce following result − STATUS Output
float[1]
Example
In the following example when which=3, calculate XN from [P, S, PR].
P is the cumulation from 0 to S of the binomial distribution. Input range: [0, 1] .
S is number of successes observed. Input range: [0,XN].
XN is number of binomial trials. Input range: [0, +infinity].
PR is the probability of success in each binomial trial. Input range: [0, 1].
Output
This will produce following result −
float[3]
Example
In the following example when which=4, calculate PR from [P, S, XN].
P is the cumulation from 0 to S of the binomial distribution. Input range: [0, 1] .
S is number of successes observed. Input range: [0,XN].
XN is number of binomial trials. Input range: [0, +infinity].
PR is the probability of success in each binomial trial. Input range: [0, 1].
Output
This will produce following result −
float[0.7]
