IDAX.PBINOM - Cumulative binomial distribution

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
