The PBINOM function returns the probability that the value of a variable that follows the
binomial distribution is smaller or equal to x.
Syntax
IDAX.PBINOM(DOUBLE x, INT8 N, DOUBLE p)
Parameter descriptions
- x
- Mandatory.
- The value that is to be computed.
- If x is 0 or less, PBINOM(x,N,p) = 0 for all positive N values, and p values in the range of 0 - 1.
- If x is greater or equal to N, PBINOM(x,N,p) = 1 for all positive N values, and p values in the
range of 0 - 1.
- Data type: DOUBLE
- N
- Mandatory.
- The number of trials.
- If N is 0 or less, PBINOM(x,N,p) is null for all x values and p values.
- Min: 1
- Data type: INT8
- p
- Mandatory.
- The probability of success.
- If p is not in the range of 0 - 1, PBINOM(x,N,p) is null for all x values and N values.
- Min: 0.00000000001
- Max: 1-0.00000000001
- Data type: DOUBLE
