As an important preprocessing technology in text categorization (TC), feature selection can improve the scalability, efficiency and accuracy of a text classifier [1]. In this paper, we propose a two-stage TC model—a fully non-parametric feature selection model. This classification model first selects features using non-parametric statistical methods, and then applies non-parametric classifiers ...

The most important impacts of climate change relate to temperature and precipitation. Precipitation is particularly important, because changes in precipitation patterns may lead to floods or droughts in different areas. Also, precipitation is a major factor in agriculture and in recent years interest has increased in learning about precipitation variability for periods of months to annual and s...

Bhadradri district of the central Telangana zone is monsoon dependent as like our country in past three decades many changes and shifts rainfall was experienced by farming community. Hence, data (1991-2020) analyzed using non parametric statistical tests i.e Mann-Kendall (MK) test Sen’s slope estimator for determining trend magnitude. The Results study revealed that Z value annual significantly...

Several reproducibility probability (RP)-estimators for the binomial, sign, Wilcoxon signed rank and Kendall tests are studied. Their behavior in terms of MSE is investigated, as well as their performances for RP-testing. Two classes of estimators are considered: the semi-parametric one, where RP-estimators are derived from the expression of the exact or approximated power function, and the non...

abstract in this research, temporal trends of reference evapotranspiration (et0) values were investigated in arid regions of iran. for this purpose, the meteorological observations collected from 11 high quality meteorological sites for a 41-year period (1965-2005) were used and statistically significant et0 trends in the monthly, seasonal and annual time basis were detected by the non-parametr...

global warming has brought about changes in meteorological variable time series. these changes, accompanied with serious human intervention in nature, has resulted in hydrological changes. so the effects can be tracked down by the trend of the time series. the purpose of this study is to analyze and compare the monthly and annual trends of temperature, precipitation as well as stream flow time ...
