MathProbabilityDensityLogistic

Calculates the value of the probability density function of logistic distribution with the mu and sigma parameters for a random variable x. In case of error it returns NaN.

double  MathProbabilityDensityLogistic(
   const double  x,             // value of random variable
   const double  mu,            // mean parameter of the distribution
   const double  sigma,         // scale parameter of the distribution
   const bool    log_mode,      // calculate the logarithm of the value, if log_mode=true, then the natural logarithm of the probability density is calculated

   );

Calculates the value of the probability density function of logistic distribution with the mu and sigma parameters for a random variable x. In case of error it returns NaN.

   );

Calculates the value of the probability density function of logistic distribution with the mu and sigma parameters for an array of random variables x[]. In case of error it returns false. Analog of the dlogis() in R.

Parameters

x

[in]  Value of random variable.

x[]

[in]  Array with the values of random variable.

mu

[in]  mean parameter of the distribution.

sigma

[in]  scale parameter of the distribution.

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.
