a simple but novel and applicable approach is proposed to solve the problem of smoothing effect of ordinary kriging estimate which is widely used in mining and earth sciences. it is based on transformation equation in which z scores are derived from ordinary kriging estimates and then rescaled by the standard deviation of sample data and the sample mean is added to the result. it bears the grea...

introduction: newborns should be evaluated immediately after birth and the traditional way of assessing is to use the apgar score. the aim of this study was to estimate the apgar score and evaluate the first 24 hour- clinical outcome of babies born at yazd hospitals. methods: in a descriptive cross-sectional study, apgar score was assessed for 462 newborns at the 4 centers of afshar, madar, kar...

To evaluate the reliability and validity of a Z-score normative EEG database for Low Resolution Electromagnetic Tomography (LORETA), EEG digital samples (2 second intervals sampled 128 Hz, 1 to 2 minutes eyes closed) were acquired from 106 normal subjects, and the cross-spectrum was computed and multiplied by the Key Institute's LORETA 2,394 gray matter pixel T Matrix. After a log10 transform o...

Calibration, the statistical consistency of forecast distributions and the observations, is a central requirement for probabilistic predictions. Calibration of continuous forecasts is typically assessed using the probability integral transform histogram. In this article, we propose significance tests based on scoring rules to assess calibration of continuous predictive distributions. For an ide...

Statistical methods based on ranking are known to be versatile and powerful techniques. Nonparametric rank tests for two-way analysis of variance have been studied by several authors, for example: rank transform (RT ) proposed by Conover and Iman (1981); asymptotic theory of RT discussed by Hora and Conover (1984), Akritas (1990) and Thompson and Ammann (1990). McKean and Vidman (1994) suggeste...
