Performs a Shapiro-Francia test of normality on the sample.

Namespace:  Meta.Numerics.Statistics
Assembly:  Meta.Numerics (in Meta.Numerics.dll) Version: 4.1.4
public static TestResult ShapiroFranciaTest(
	this IReadOnlyList<double> sample


Type: System.Collections.GenericIReadOnlyListDouble
The sample to test for normality.

Return Value

Type: TestResult
The result of the test.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type IReadOnlyListDouble. When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).
ArgumentNullExceptionsample is .
InsufficientDataExceptionThere are fewer than 16 values in the sample.

Our current implementation requires the sample to contain at least 16 values. While the Shapiro-Francia test is perfectly well-defined for smaller samples, the parameterization of the null distribution for such small samples requires special handling that we have not yet coded.
