Detailed Description

Computes statistical moments over a rolling window of values.

Mean and variance are computed directly from the sample buffer, avoiding numerical drift from incremental update algorithms.

Example: RollingStats stats(100); // 100-sample window stats.add(42); stats.add(43); double mean = stats.mean(); double stddev = stats.stddev();

Constructor & Destructor Documentation

RollingStats()

sol3::math::RollingStats::RollingStats ( size_t  window_size )

explicit

Construct a rolling statistics tracker with a fixed window size.

Parameters

window_size

Maximum number of samples to track

Member Function Documentation

add()

template<typename T >

void sol3::math::RollingStats::add ( T  value )

inline

Add a new value to the rolling window. If the window is full, the oldest value is removed.

clear()

void sol3::math::RollingStats::clear

(

)

Clear all samples and reset statistics.

count()

size_t sol3::math::RollingStats::count

(

)

const

Number of samples currently in the window.

isFull()

bool sol3::math::RollingStats::isFull

(

)

const

Returns true if the window is full.

mean()

double sol3::math::RollingStats::mean

(

)

const

Mean (first moment).

stddev()

double sol3::math::RollingStats::stddev

(

)

const

Standard deviation (square root of variance).

variance()

double sol3::math::RollingStats::variance

(

)

const

Variance (second central moment). Uses Bessel's correction (n-1) for sample variance.

windowSize()

size_t sol3::math::RollingStats::windowSize

(

)

const

Maximum window size.
