Detailed Description

Data structure for building a FLinearFunction based on linear regression.

Caches the sums required for linear regression: when an old sample is replaced, the old value is subtracted and the new value added. This effectively avoids the summing all elements whenever the a new sample is added.

Returns: Whether no samples have been added.

Member Data Documentation

◆ CachedSums

FLinearRegressionArgs UE::TimeManagement::FCachedLinearRegressionSums::CachedSums

Caches the sums of the samples. Whenever a sample is replaced, the old value is subtracted and the new value added to the respective sums.

◆ Samples

TModuloCircularBuffer<FVector2d> UE::TimeManagement::FCachedLinearRegressionSums::Samples

Holds the samples based off of which the samples are created.
