AddSampleAndUpdateSums() [1/2]

void UE::TimeManagement::AddSampleAndUpdateSums ( const FVector2d &  InSample, FCachedLinearRegressionSums &  InCachedSums  )

inline

AddSampleAndUpdateSums() [2/2]

void UE::TimeManagement::AddSampleAndUpdateSums	(	const FVector2d &	InSample,
		TModuloCircularBuffer< FVector2d > &	InSamples,
		FLinearRegressionArgs &	InCachedArguments
	)

Adds a sample and updates the associated sums.

ComputeLinearRegressionInputArgs()

FLinearRegressionArgs UE::TimeManagement::ComputeLinearRegressionInputArgs

(

const TConstArrayView< FVector2d > &

InBuffer

)

Returns

The arguments required to compute linear regression based off of InBuffer. FVector2d::X is the independent variable, and FVector2d::Y the associated dependent variable value for the X.

ComputeLinearRegressionSlopeAndOffset() [1/2]

bool UE::TimeManagement::ComputeLinearRegressionSlopeAndOffset	(	const FLinearRegressionArgs &	InArgs,
		double &	OutSlope,
		double &	OutOffset
	)

Computes the coefficients for a linear function by using linear regression.

Parameters

InArgs	The arguments required to compute linear regression
OutSlope	The slope for the linear regression. The a in "f(x) = a*x + b".
OutOffset	The offset for the linear regression. The b in "f(x) = a*x + b".

Returns

True if the function was defined. False if the linear regression function was not defined, i.e. was no correlation.

Note

Sets OutSlope and OutOffset to 0 when the function is not defined.

ComputeLinearRegressionSlopeAndOffset() [2/2]

bool UE::TimeManagement::ComputeLinearRegressionSlopeAndOffset ( const FLinearRegressionArgs &  InArgs, FLinearFunction &  OutFunction  )

inline

Util that puts the sets the values of the linear function.
