the authors of the present paper studied some aspects of hydro and agrometeorological phenomena in terms of humidness, dryness and crop growing periods over india. revised water balance model is used to obtain the above and the results are examined during the two half centuries i.e 1901 to 1950 and 1951 to 1995 in delineating the climate change impacts over india. palmer drought severity index ...

We provide an overview of the probability and statistical tools underlying the extreme value theory, which aims to predict occurrence of rare events. Firstly, we explain that the asymptotic distribution of extreme values belongs, in some sense, to the family of the generalised extreme value distributions which depend on a real parameter, called the extreme value index. Secondly, we discuss stat...

The reliability of extreme wind speed predictions at large mean recurrence intervals (MRI) is assessed by bootstrapping samples from representative known distributions. classical asymptotic generalized value distribution (GEV) and the Pareto (GPD) are compared with a contemporary sub-asymptotic Gumbel that accounts for incomplete convergence to correct asymptote. model implemented through modif...

A fundamental problem in citation analysis is the prediction of the long-term citation impact of recent publications. We propose a model to predict a probability distribution for the future number of citations of a publication. Two predictors are used: The impact factor of the journal in which a publication has appeared and the number of citations a publication has received one year after its a...
