FixedLimitSeries Class

Holds the analysis results for a chart baseline whose center line and control limits are constant over the analyzed run.

Remarks

A fixed-limit series is the building block for chart families in which the control limits do not depend on individual sample sizes or time position. Typical users include the Individuals, Moving Range, XBar, R, S, C, and NP charts with constant sample size.

Two distinct modes of use are supported:

Fitted mode — all properties are available. Use the constructor that accepts values, index, centerLine, lowerControlLimit, upperControlLimit, and sigma.
Deployed mode — only the fitted parameters (CenterLine, LowerControlLimit, UpperControlLimit, and Sigma) are available. Accessing Values or Index in this mode throws InvalidOperationException. Use Deploy() to obtain a deployed instance.

Instances of this class are immutable once constructed.

Constructors

FixedLimitSeries

Initializes a new FixedLimitSeries in Fitted mode with analyzed data and fitted parameters.

Properties

CenterLine	Gets the center line value of this control chart series. (Overrides ControlSeries.CenterLine)
Index	Gets the index that provides labels or positions for the analyzed data points, or null if no index was supplied. (Overrides ControlSeries.Index)
LowerControlLimit	Gets the lower control limit of this control chart series.
LowerControlLimits	Gets the lower control limit as a constant vector. Each element of the returned vector equals LowerControlLimit. (Overrides ControlSeries.LowerControlLimits)
Sigma	Gets the within-subgroup or within-sample standard deviation estimate used to compute the control limits.
UpperControlLimit	Gets the upper control limit of this control chart series.
UpperControlLimits	Gets the upper control limit as a constant vector. Each element of the returned vector equals UpperControlLimit. (Overrides ControlSeries.UpperControlLimits)
Values	Gets the analyzed data points for this series. (Overrides ControlSeries.Values)

Methods

Deploy	Returns a new FixedLimitSeries in Deployed mode that retains the fitted parameters but discards the analyzed data and index.
Diagnose	Runs assumption diagnostics on the analyzed values in this series. (Overrides ControlSeries.Diagnose(ControlRuleSet, Nullable<TestOfNormality>, Double))
Equals	Determines whether the specified object is equal to the current object. (Inherited from Object)
EvaluateRules	Evaluates a set of control rules against this series. (Inherited from ControlSeries)
GetHashCode	Serves as the default hash function. (Inherited from Object)
GetType	Gets the Type of the current instance. (Inherited from Object)
ToString	Returns a string that represents the current object. (Inherited from Object)
