Detailed Description

template<typename FloatType>
class StatisticsAccumulator< FloatType >

A class that measures various statistics about a series of floating point values that it is given.

Constructor & Destructor Documentation

StatisticsAccumulator()

template<typename FloatType >

StatisticsAccumulator< FloatType >::StatisticsAccumulator ( )

default

Constructs a new StatisticsAccumulator.

Member Function Documentation

addValue()

template<typename FloatType >

void StatisticsAccumulator< FloatType >::addValue ( FloatType  v )

noexcept

Add a new value to the accumulator.

This will update all running statistics accordingly.

References jassert, and juce_isfinite().

reset()

template<typename FloatType >

void StatisticsAccumulator< FloatType >::reset ( )

noexcept

Reset the accumulator.

This will reset all currently saved statistcs.

getAverage()

template<typename FloatType >

FloatType StatisticsAccumulator< FloatType >::getAverage ( ) const

noexcept

Returns the average (arithmetic mean) of all previously added values.

If no values have been added yet, this will return zero.

getVariance()

template<typename FloatType >

FloatType StatisticsAccumulator< FloatType >::getVariance ( ) const

noexcept

Returns the variance of all previously added values.

If no values have been added yet, this will return zero.

getStandardDeviation()

template<typename FloatType >

FloatType StatisticsAccumulator< FloatType >::getStandardDeviation ( ) const

noexcept

Returns the standard deviation of all previously added values.

If no values have been added yet, this will return zero.

References StatisticsAccumulator< FloatType >::getVariance().

getMinValue()

template<typename FloatType >

FloatType StatisticsAccumulator< FloatType >::getMinValue ( ) const

noexcept

Returns the smallest of all previously added values.

If no values have been added yet, this will return positive infinity.

getMaxValue()

template<typename FloatType >

FloatType StatisticsAccumulator< FloatType >::getMaxValue ( ) const

noexcept

Returns the largest of all previously added values.

If no values have been added yet, this will return negative infinity.

getCount()

template<typename FloatType >

size_t StatisticsAccumulator< FloatType >::getCount ( ) const

noexcept

Returns how many values have been added to this accumulator.
