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));
}
