Stats.CorrelationAs Method

Definition

Namespace: Numerics.NET.Statistics
Assembly: Numerics.NET (in Numerics.NET.dll) Version: 9.0.3

Overload List

CorrelationAs<T, TResult>(Vector<T>, Vector<T>) Gets the Pearson correlation coefficient between two sets of values.
CorrelationAs<T, TResult>(ReadOnlySpan<T>, ReadOnlySpan<T>, Boolean) Gets the Pearson correlation coefficient between two arrays.

CorrelationAs<T, TResult>(Vector<T>, Vector<T>)

Gets the Pearson correlation coefficient between two sets of values.
C# 
public static TResult CorrelationAs<T, TResult>(
	this Vector<T> values1,
	Vector<T> values2
)

Parameters

values1  Vector<T>
A numerical vector.
values2  Vector<T>
A numerical vector.

Type Parameters

T
The type of the elements of values1 and values2.
TResult
The type of the result.

Return Value

TResult
The correlation between the two sets of values.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type Vector<T>. 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).

Exceptions

ArgumentNullException

values1 is null.

-or-

values2 is null.

DimensionMismatchException

The length of values1 does not equal the length of values2.

CorrelationAs<T, TResult>(ReadOnlySpan<T>, ReadOnlySpan<T>, Boolean)

Gets the Pearson correlation coefficient between two arrays.
C# 
public static TResult CorrelationAs<T, TResult>(
	this ReadOnlySpan<T> values1,
	ReadOnlySpan<T> values2,
	bool skipMissingValues
)

Parameters

values1  ReadOnlySpan<T>
A numerical vector.
values2  ReadOnlySpan<T>
A numerical vector.
skipMissingValues  Boolean
Optional. Specifies whether missing values should be excluded from the calculation. The default is false.

Type Parameters

T
The type of the elements of values1 and values2.
TResult
The type of the result.

Return Value

TResult
The correlation between values1 and values2.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type ReadOnlySpan<T>. 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).

Exceptions

DimensionMismatchException

The length of values1 does not equal the length of values2.
