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 ...

For the exponential failure law with known location parameter, the minimum variance single observation unbiased estimator of the scale parameter (average life) is investigated. It is shown that if the ...

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 ...
