Overload List

PopulationStandardDeviation(DateTime[]) Returns the population standard deviation of the elements of an array.
PopulationStandardDeviation(Vector<DateTime>) Returns the population standard deviation of the elements of a numerical variable.
PopulationStandardDeviation<T>(Vector<T>) Returns the population standard deviation of the elements of a vector.
PopulationStandardDeviation<T>(T[], Boolean) Returns the population standard deviation of the elements of an array.
PopulationStandardDeviation<T>(IEnumerable<T>, Boolean) Returns the population standard deviation of the elements of an array.
PopulationStandardDeviation<T>(ReadOnlySpan<T>, Boolean) Returns the population standard deviation of the elements of a span.

PopulationStandardDeviation(DateTime[])

Returns the population standard deviation of the elements of an array.
C#
public static TimeSpan PopulationStandardDeviation(
	DateTime[] values
)

Parameters

values  DateTime[]
An DateTime array.

Return Value

TimeSpan
The standard deviation of the elements of values.

Remarks

The standard deviation is a TimeSpan value.

Exceptions

ArgumentNullException

values is null.

PopulationStandardDeviation(Vector<DateTime>)

Returns the population standard deviation of the elements of a numerical variable.
C#
public static TimeSpan PopulationStandardDeviation(
	Vector<DateTime> values
)

Parameters

values  Vector<DateTime>
A Vector<T> of DateTime.

Return Value

TimeSpan
The standard deviation of the elements of values.

Exceptions

ArgumentNullException

values is null.

PopulationStandardDeviation<T>(Vector<T>)

Returns the population standard deviation of the elements of a vector.
C#
public static double PopulationStandardDeviation<T>(
	this Vector<T> values
)

Parameters

values  Vector<T>
A vector.

Type Parameters

T
The type of the elements of values.

Return Value

Double
The standard deviation of the elements 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

values is null.

PopulationStandardDeviation<T>(T[], Boolean)

Returns the population standard deviation of the elements of an array.
C#
public static double PopulationStandardDeviation<T>(
	this T[] values,
	bool skipMissingValues = false
)

Parameters

values  T[]
An array of values.
skipMissingValues  Boolean  (Optional)
Optional. Specifies whether missing values should be excluded from the calculation. The default is false.

Type Parameters

T
The type of the elements of values.

Return Value

Double
The standard deviation of the elements of values.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type 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

values is null.

PopulationStandardDeviation<T>(IEnumerable<T>, Boolean)

Returns the population standard deviation of the elements of an array.
C#
public static double PopulationStandardDeviation<T>(
	IEnumerable<T> values,
	bool skipMissingValues = false
)

Parameters

values  IEnumerable<T>
An object that implements IEnumerable<Double>.
skipMissingValues  Boolean  (Optional)
Optional. Specifies whether missing values should be excluded from the calculation. The default is false.

Type Parameters

T
The type of the elements of values.

Return Value

Double
The standard deviation of the elements of values.

Remarks

The population standard deviation is the square root of the population variance.

No observed values returns NaN; one finite observed value returns zero.

Exceptions

ArgumentNullException

values is null.

PopulationStandardDeviation<T>(ReadOnlySpan<T>, Boolean)

Returns the population standard deviation of the elements of a span.
C#
public static double PopulationStandardDeviation<T>(
	this ReadOnlySpan<T> values,
	bool skipMissingValues = false
)

Parameters

values  ReadOnlySpan<T>
A span of values.
skipMissingValues  Boolean  (Optional)
Optional. Specifies whether missing values should be excluded from the calculation. The default is false.

Type Parameters

T
The type of the elements of values.

Return Value

Double
The standard deviation of the elements of values.

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).
