Functions ¶

func Estimate ¶

func Estimate(fe *FilterEstimate) big.Int

Returns the Q.0 position estimate of the filter

func ExtrapolatedCumSumOfRatio ¶

func ExtrapolatedCumSumOfRatio(delta abi.ChainEpoch, relativeStart abi.ChainEpoch, estimateNum, estimateDenom FilterEstimate) big.Int

Extrapolate the CumSumRatio given two filters. Output is in Q.128 format

Types ¶

type FilterEstimate ¶

type FilterEstimate struct {
	PositionEstimate big.Int // Q.128
	VelocityEstimate big.Int // Q.128
}

Alpha Beta Filter "position" (value) and "velocity" (rate of change of value) estimates Estimates are in Q.128 format

func NewEstimate ¶

func NewEstimate(position, velocity big.Int) FilterEstimate

Create a new filter estimate given two Q.0 format ints.

func (*FilterEstimate) MarshalCBOR ¶

func (t *FilterEstimate) MarshalCBOR(w io.Writer) error

func (*FilterEstimate) UnmarshalCBOR ¶

func (t *FilterEstimate) UnmarshalCBOR(r io.Reader) (err error)
