When control limits are determined from the input data, three methods (referred to as default, MVLUE, and RMSDF) are available for estimating . If the unknown standard deviation is constant across ...

The sample standard deviation is a commonly used estimator of the population scale. However, it is sensitive to outliers and may not remain bounded when a single data point is replaced by an arbitrary ...

For all its limitations, value-at-risk remains a key measure in risk management and regulatory capital calculations, and forms the bedrock of many strategic business decisions. So it is disconcerting ...
