In this paper, a group acceptance sampling plan (GASP) is introduced for the situations when lifetime of the items … determined when the consumer's risk and the test termination time are specified. The proposed sampling plan is compared with the … existing sampling plan. It is concluded that the proposed sampling plan performs better than the existing plan in terms of …

Statistical modeling techniques-and factor models in particular-are extensively used in practice, especially in the insurance and finance industry, where many risks have to be accounted for. In risk management applications, it might be important to analyze the situation when fixing the value of...

We develop a distribution regression model under endogenous sample selection. This model is a semiparametric generalization of the Heckman selection model that accommodates much rich patterns of heterogeneity in the selection process and effect of the covariates. The model applies to continuous,...

The aim of this work was to test how returns are distributed across multiple asset classes, markets and sampling …. Finally, we show how sampling and distribution of returns are strictly connected. This is of great importance as, for example …

It is well documented in the literature that the sample skewness and excess kurtosis can be severely biased in finite samples. In this paper, we derive analytical results for their finite-sample biases up to the second order. In general, the bias results depend on the cumulants (up to the sixth...
