# MathCumulativeDistributionT

Calculates the value of the Student's t-distribution function with the nu parameter for a random variable x. In case of error it returns NaN.

Calculates the value of the Student's t-distribution function with the nu parameter for an array of random variables x[]. In case of error it returns false. Analog of the pt() in R.

Parameters

x

[in]  Value of random variable.

x[]

[in]  Array with the values of random variable.

nu

[in]  Parameter of distribution (number of degrees of freedom).

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.

error_code

[out]  Variable to store the error code.

result[]

[out]  Array for values of the probability function.
