# MathCumulativeDistributionNegativeBinomial

Calculates the value of the probability distribution function for negative binomial law with the r and p parameters for a random variable x. In case of error it returns NaN.

Parameters

x

[in]  Value of random variable.

x[]

[in]  Array with the values of random variable.

r

[in]  Number of successful tests.

p

[in]  Probability of success.

tail

[in]  Flag of calculation, if true, then the probability of random variable not exceeding x is calculated.

log_mode

[in]  Flag to calculate the logarithm of the value, if log_mode=true, then the natural logarithm of the probability is calculated.

[out]  Variable to store the error code.

result[]

[out]  Array for values of the probability function.
