Definition

Namespace: Numerics.NET.Statistics.ProcessControl
Assembly: Numerics.NET (in Numerics.NET.dll) Version: 10.4.0

Overload List

P(ReadOnlySpan<Double>, ReadOnlySpan<Double>) Computes a P (fraction nonconforming) chart from spans of defect counts and subgroup sample sizes.
P(Vector<Double>, Vector<Double>) Computes a P (fraction nonconforming) chart from a vector of defect counts and a vector of subgroup sample sizes.
P(Vector<Double>, Vector<Double>, RateBaseline) Computes a P (fraction nonconforming) chart from a vector of defect counts and sample sizes in Phase II mode, evaluating against a frozen baseline from a prior Phase I analysis.

P(ReadOnlySpan<Double>, ReadOnlySpan<Double>)

Computes a P (fraction nonconforming) chart from spans of defect counts and subgroup sample sizes.
C# 
public static PChartData P(
	ReadOnlySpan<double> defectCounts,
	ReadOnlySpan<double> sampleSizes
)

Parameters

defectCounts  ReadOnlySpan<Double>
The ordered sequence of nonconforming-unit counts, one per subgroup.
sampleSizes  ReadOnlySpan<Double>
The ordered sequence of subgroup sample sizes, one per subgroup. All values must be positive.

Return Value

PChartData
The chart-ready data for the P chart.

Exceptions

ArgumentException The inputs are empty, have mismatched lengths, contain non-finite values, contain negative counts, contain non-positive sample sizes, or any count exceeds its corresponding sample size.

P(Vector<Double>, Vector<Double>)

Computes a P (fraction nonconforming) chart from a vector of defect counts and a vector of subgroup sample sizes.
C# 
public static PChartData P(
	Vector<double> defectCounts,
	Vector<double> sampleSizes
)

Parameters

defectCounts  Vector<Double>
The ordered sequence of nonconforming-unit counts, one per subgroup.
sampleSizes  Vector<Double>
The ordered sequence of subgroup sample sizes, one per subgroup. All values must be positive.

Return Value

PChartData
The chart-ready data for the P chart.

Exceptions

ArgumentNullExceptiondefectCounts or sampleSizes is null.
ArgumentException The inputs are empty, have mismatched lengths, contain non-finite values, contain negative counts, contain non-positive sample sizes, or any count exceeds its corresponding sample size.

P(Vector<Double>, Vector<Double>, RateBaseline)

Computes a P (fraction nonconforming) chart from a vector of defect counts and sample sizes in Phase II mode, evaluating against a frozen baseline from a prior Phase I analysis.
C# 
public static PChartData P(
	Vector<double> defectCounts,
	Vector<double> sampleSizes,
	RateBaseline baseline
)

Parameters

defectCounts  Vector<Double>
The ordered sequence of nonconforming-unit counts, one per subgroup.
sampleSizes  Vector<Double>
The ordered sequence of subgroup sample sizes, one per subgroup. All values must be positive.
baseline  RateBaseline
The frozen Phase I baseline to evaluate against.

Return Value

PChartData
The chart-ready data for the P chart, with control limits derived from the frozen baseline.

Exceptions

ArgumentNullExceptiondefectCounts, sampleSizes, or baseline is null.
