IndividualsMovingRangeChartSet Class

A v2 SPC chart for monitoring individual observations and their moving ranges. Implements the full Unfitted → Fitted → Deployed → Apply lifecycle defined by ControlChart.

C++/CLI

    end

Inheritance: Object → ControlChart → ControlChart<IndividualsMovingRangeChartSet> → IndividualsMovingRangeChartSet

Remarks

The IndividualsMovingRangeChartSet (I–MR chart) is used when one measurement is collected per time period. Phase-I control limits are estimated from a baseline data set; the deployed chart can then be serialized and applied to future production batches without re-estimation.

Typical usage:

double[] baseline = { 9, 11, 10, 12, 8, 10, 9, 11, 10, 10 };

// Phase I — establish limits
IndividualsMovingRangeChartSet chart = new IndividualsMovingRangeChartSet(Vector.Create(baseline));
chart.Analyze();

// Deploy for production monitoring
IndividualsMovingRangeChartSet deployed = (IndividualsMovingRangeChartSet)chart.Deploy();

// Persist and restore
string json = deployed.ToJson();
IndividualsMovingRangeChartSet restored = IndividualsMovingRangeChartSet.FromJson(json);

// Phase II — apply to new observations
double[] production = { 10, 9, 11, 12, 10 };
IndividualsMovingRangeChartSet applied = (IndividualsMovingRangeChartSet)restored.Apply(
    Vector.Create(production));

Constructors

IndividualsMovingRangeChartSet

Initializes a new IndividualsMovingRangeChartSet in the Unfitted state from a vector of observations.

Properties

IndividualsSeries	Gets the Individuals series. Contains the analyzed observations and the computed control limits.
MovingRangesSeries	Gets the Moving Ranges series. Contains the computed moving range values and the corresponding control limits.
MovingRangeWidth	Gets the width of the moving range window used by this chart.
SigmaEstimator	Gets the sigma estimator used to compute the Individuals chart control limits.
State	Gets the current lifecycle state of this chart. (Inherited from ControlChart)

Methods

Analyze	Performs phase-I analysis, establishing control limits and transitioning the chart from Unfitted to Fitted. (Inherited from ControlChart)
Apply	Applies new observations to this Deployed chart and returns a new TChart in the Fitted state. (Inherited from ControlChart<TChart>)
CreateDeployed	Creates an IndividualsMovingRangeChartSet directly in the Deployed state from externally supplied fitted parameters.
Deploy	Creates a new TChart in the Deployed state from this Fitted chart. (Inherited from ControlChart<TChart>)
Diagnose	Produces a diagnostic report for the current chart state. (Inherited from ControlChart)
Equals	Determines whether the specified object is equal to the current object. (Inherited from Object)
FromJson	Reconstructs an IndividualsMovingRangeChartSet from a JSON string previously produced by ToJson().
GetHashCode	Serves as the default hash function. (Inherited from Object)
GetType	Gets the Type of the current instance. (Inherited from Object)
ToJson	Serializes this IndividualsMovingRangeChartSet to a JSON string.
ToString	Returns a string that represents the current object. (Inherited from Object)
