# MathProbabilityDensityGeometric

Calculates the value of the probability mass function of geometric distribution with the p parameter for a random variable x. In case of error it returns NaN.

 double  MathProbabilityDensityGeometric(    const double  x,             // value of random variable (integer)    const double  p,             // parameter of the distribution (probability of event occurrence in one test)    const bool    log_mode,      // calculate the logarithm of the value, if log_mode=true, then the natural logarithm of the probability density is calculated    int&          error_code     // variable to store the error code    );

Calculates the value of the probability mass function of geometric distribution with the p parameter for a random variable x. In case of error it returns NaN.

Calculates the value of the probability mass function of geometric distribution with the p parameter for an array of random variables x[]. In case of error it returns false. Analog of the dgeom() in R.

Calculates the value of the probability mass function of geometric distribution with the p parameter for an array of random variables x[]. In case of error it returns false.

Parameters

x

[in]  Value of random variable.

x[]

[in]  Array with the values of random variable.

p

[in]  Parameter of the distribution (probability of event occurrence in one test).

log_mode

[in]  Flag to calculate the logarithm of the value. If log_mode=true, then the natural logarithm of the probability density is returned.

error_code

[out]  Variable to store the error code.

result[]

[out]  Array for values of the probability density function.
