poisscdf

Description

Poisson distribution cdf

Syntax

double poisscdf( const int iK, double rlamda, int iTail = TAILED_TEST_DISC_LOWER, int * nFail = NULL )

Parameters

iK

[input]integer which defines the required probabilities.

rlamda

[input]parameter of the Poisson distribution.

iTail

[input] int,

TAILED_TEST_DISC_LOWER. lower tail. .

TAILED_TEST_DISC_UPPER. upper tail. .

TAILED_TEST_DISC_POINT. point probability. .

nFail

[output] on successful exit, it returns the NAG error code NE_NOERROR; if an error or warning has been detected, then it returns the specific error or warning code.

Return

Returns Poisson distribution cdf

Examples

EX1

void poisscdf_ex1()
{
        double iK[]= {0.25, 1.5, 2.75};
        double r = 0.75;
        for(int ii = 0; ii<3; ii++)
                printf("%f     %f:     %f\n", iK[ii], r, poisscdf(iK[ii],r));
}
