Detailed Description

Calculator for statistical parameters of a distribution.

Use one of the add() functions to add new values to the calculator.

Then you can call one of the functions that return a statistical parameter (average, variance, etc.). When one of these functions is called, all the other parameters are also computed. The computation is valid until a new value is added to the calculator.

If the calculator object was constructed with a limited number of samples, only the last "n" samples are used to compute the statistical parameters.

◆ statpars() [1/2]

mlib::statpars::statpars ( int n = 0 )

Constructor for calculator class.

Parameters

n	number of samples. If not 0, only the last n samples are used for computations.
