discrete_uniform_cdf
Evaluates the discrete uniform cumulative distribution function (CDF).
Synopsis
#include<imsls.h>
floatimsls_f_discrete_uniform_cdf(int ix, int n)
The type double function is imsls_d_discrete_uniform_cdf.
Required Arguments
intix (Input)
Argument for which the discrete uniform CDF is to be evaluated. ix must be positive.
intn (Input)
Scale parameter. n must be positive.
Return Value
The probability that a discrete uniform random variable takes a value less than or equal to ix. A value of NaN is returned if an input value is in error.
Description
The function discrete_uniform_cdf evaluates the discrete uniform cumulative distribution function (CDF) with scale parameter n, defined
where I = ix and N = n.
Example
In this example, we evaluate the discrete uniform CDF at ix = 3, n = 5.
#include <imsls.h>
#include <stdio.h>
int main()
{
int ix = 3;
int n = 5;
float p;
p = imsls_f_discrete_uniform_cdf(ix, n);
printf("The probability that a discrete uniform ");
printf("random variable\nwith scale ");
printf("parameter n = %1i is less than ", n);
printf("or equal to %li\nis %6.4f\n\n", ix, p);
}
Output
The probability that a discrete uniform random variable
with scale parameter n = 5 is less than or equal to 3
is 0.6000
