Detailed Description

estimation of the expectation and standard devation of a random variable.

NAME: ExpecVar - estimation of the expectation and standard devation of a random variable

DESCRIPTION:

The class offers estimators for the expectation and the standard deviation of a random variable. The class offers functions for updating statistics and printing of intermediate results during sampling as well as functions for returning the calculated statistical quanities.

Member Function Documentation

void ExpecVar::estimator ( ) [protected]

Reimplemented in Moments.

real ExpecVar::getExpec ( ) [inline]

returns the current estimated expectation value.

real ExpecVar::getStDev ( ) [inline]

returns the current estimated standard deviation value.

void ExpecVar::init ( ) [inline]

resets and initializes internal data structures. Reimplemented from EmpiricalStatistics. Reimplemented in Moments, and Extremes.

void ExpecVar::intermediateResults ( Os os )

prints the curent expectation and standard deviation values. Reimplemented in Moments, and Extremes.

void ExpecVar::printResults ( Os os )

same as "intermediateResults". Reimplemented in Moments, and Extremes.

void ExpecVar::update ( real random_variable )

adds a new sample to the estimators. Reimplemented in Moments, and Extremes.
