In this paper, we propose a new unbiased stochastic derivative estimator in a framework that can handle discontinuous sample performances with structural parameters. This work extends the three most ...

Precise criteria have been published recently for obtaining unbiased ratio estimators of structural parameters, defined in an n-dimensional opaque specimen, from observations in lower-dimensional ...

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 ...
