In the paper, we propose a general method for statistical performance evaluation. The method incorporates various statistical metrics and automatically selects an appropriate statistical metric according to the problem parameters. Empirically, We compare the performance of five representative statistical metrics under different conditions through simulation. They are expected loss, Friedman sta...

els based on alternative bud development theories applied to Betula pendula Roth data. Statistical testing based on the bootstrap method showed that the mean square errors (MSE) of the predicted bud-burst dates of two models, in which the start of ontogenetic development depended on dormancy development only, did not differ significantly. However, the MSE of the model in which the start of onto...

Comparison of two methods for determining a substance is a common procedure in clinical chemistry. Almost without exception, normal theory statistics are used with the tacit assumption that the data under test show gaussian distributions. Experience has led us to question this assumption for populations of differences between values obtained by two methods applied to common samples and for popu...

Recently a number of modeling techniques have been developed for data mining and machine learning in relational and network domains where the instances are not independent and identically distributed (i.i.d.). These methods specifically exploit the statistical dependencies among instances in order to improve classification accuracy. However, there has been little focus on how these same depende...

A variety of forensic cases need to be based on haploid DNA. The statistical evaluation of the genetic evidence in such cases requires particular attention and methods. There may be considerable differences between databases and this must be accounted for when there is uncertainty about the population origin of the perpetrator. We here assume access to the relevant databases sampled from popula...

Statistical evaluation of historical dike failure mechanism The failure mechanism of flood protection dikes includes physical (geotechnical, seepage) processes leading to a dike breach. An awareness of the failure mechanism is required directly in dike stability calculations and indirectly for risk calculations. Statistics of historical data indicate among others the distribution and frequency ...

This paper reports on investigations concerning the convergence of the reconstruction process in fractal coding schemes from a statistical point of view. For a rather general family of “fractal operators” a necessary and sufficient condition for the convergence based on the spectral radius of the fractal operator is provided. Emerging from this condition the probability density function (pdf) o...

the evaluation of prevalence and appearing the social disorders involve having exact statistical information during a fixed time series. in iran, unfortunoutiely, there is no access to this kind of information - at least in this regard. in some social disorders which originally have risen some misunderstanding and disagreement in their definitions, importance, and soon, the lack of statistic in...

The γ-index test has been commonly adopted to quantify the degree of agreement between a reference dose distribution and an evaluation dose distribution. Monte Carlo (MC) simulation has been widely used for the radiotherapy dose calculation for both clinical and research purposes. The goal of this work is to investigate both theoretically and experimentally the impact of the MC statistical fluc...
