the innovation of a statistical model to estimate dependable rainfall (dr) and develop it for determination and classification of drought and wet years of iran

آب حاصل از بارش منبع تأمین نیازهای بی شمار جانداران به ویژه انسان است و هرگونه کاهش در کم و کیف آن مستقیماً حیات موجودات زنده را تحت تأثیر منفی قرار می دهد. نوسان سال به سال بارش از ویژگی های اساسی و بسیار مهم بارش های سالانه ایران محسوب می شود که آثار زیان بار آن در تمام عرصه های اقتصادی، اجتماعی و حتی سیاسی- امنیتی به نحوی منعکس می شود. چون میزان آب ناشی از بارش یکی از مولفه های اصلی برنامه ...

A New Model for Text Coherence Evaluation using Statistical Characteristics

Preparation of Groundwater Potential Map (Springs) of Sierra Watershed Using Bivariate Statistical Model and Frequency Ratio

In this study, using the frequency ratio (FR) model, an attempt has been made to identify areas with high groundwater potential of the Sira catchment. Effective factors for preparing groundwater potential map including slope aspect, slope percentage, slope length (LS), Elevation, stream power index (SPI), topographic wetness index (TWI), plan curvature, distance to rivers, distance to roads, di...

Univariate statistical analysis with fuzzy data

Statistical data are frequently not precise numbers but more or less non-precise, also called fuzzy. Measurements of continuous variables are always fuzzy to a certain degree. Therefore histograms and generalized classical statistical inference methods for univariate fuzzy data have to be considered. Moreover Bayesian inference methods in the situation of fuzzy a-priori information and fuzzy da...
