public static ProcessAnalysisResult<NpChartData> AnalyzeNP(
	Vector<double> defectCounts,

Visual Basic

Public Shared Function AnalyzeNP ( 
	defectCounts As Vector(Of Double),
	sampleSize As Double,
	Optional ruleSet As ControlRuleSet = Nothing,
	Optional baseline As StandardBaseline = Nothing
) As ProcessAnalysisResult(Of NpChartData)

C++/CLI

public:
static ProcessAnalysisResult<NpChartData^>^ AnalyzeNP(
	Vector<double>^ defectCounts, 
	double sampleSize, 
	ControlRuleSet^ ruleSet = nullptr, 
	StandardBaseline^ baseline = nullptr
)

static member AnalyzeNP : 
        defectCounts : Vector<float> * 
        sampleSize : float * 
        ?ruleSet : ControlRuleSet * 
        ?baseline : StandardBaseline 
(* Defaults:
        let _ruleSet = defaultArg ruleSet null
        let _baseline = defaultArg baseline null
*)
-> ProcessAnalysisResult<NpChartData>

Parameters

defectCounts Vector<Double>: The ordered sequence of defect counts, one per subgroup.
sampleSize Double: The constant sample size used for all subgroups.
ruleSet ControlRuleSet (Optional): Optional rule set used to evaluate rules on the NP series. When null no rule evaluation is performed.
baseline StandardBaseline (Optional): When non-null, runs in Phase II mode: the count center line, limits, and sample size are taken from the frozen baseline; sampleSize is ignored. Defaults to null (Phase I).

Return Value

ProcessAnalysisResult<NpChartData>
A ProcessAnalysisResult<TChartData> containing chart data and diagnostics.

Exceptions

ArgumentNullException	defectCounts is null.
ArgumentException	The input is empty, contains non-finite values, or contains invalid defect counts.
ArgumentOutOfRangeException	sampleSize is not positive.
