Parameters

startIndex: Type: System Int32
The 0-based index of the first buffered value to consider.

endIndex: Type: System Int32
The 0-based index of the last buffered value to consider.

Return Value

Type: Double

The returned standard deviation.

Exceptions

Exception	Condition
ArgumentException	startIndex is less than 0 or startIndex is greater than or equal to NumBufferedValues.
ArgumentException	endIndex is not cogNoIndex and endIndex is less than startIndex or endIndex is greater than or equal to NumBufferedValues.
CogDataAnalysisAllInvalidValuesException	All of the values within the supplied range are invalid.

Remarks

The standard deviation of the specified range of buffered values. An index of 0 represents the oldest value; an index of NumBufferedValues - 1 represents the most recent value.
