We present their spatio-temporal counterparts and give examples of these models, based on spatio-temporal covariance functions which are separable and non-separable in space and time.

Furthermore, we also establish the asymptotic behavior of the above additive functional equations.

The aim of this study is to generalize this method to two dimensional space so that the marginals would have T − X distributions. So, several examples and properties of this family have been presented. As an application, a special distribution of this family, called bivariate Weibull-Rayleigh-Rayleigh, is fitted to a data set and is shown to have a better fit.

Information resides in neurons as molecular and ionic events and thus different types of memory are created. The aim of this study was to determine the effect of light waves of different frequencies on human short-term or long-term memory. The software programming for this study was based on previewing numbers in the brain hemispheres. The numbers that emerge in parts of a triple screen are sufficiently low contrast that the eye can put a spin on them so that the yellow spots do not have any number image, and the images resulting from the emergences are only previewable in one brain hemisphere; this is based on the temporal and nasal neural structure of the visual areas. Thus, the numbers only become possible pictures in both hemispheres when they appear in the central part of the triple screen. In series A the reaction time difference between the first ...

The most important consequences of climate change include increase of average temperature of the Earth, increase of extreme climate phenomena such as flood, corn snow, thermal waves and untimely colds. Using different climate models and having climatic forecast based on nature of their long-term time interval play a very valuable role in management of extreme phenomena. This research aims to forecast early and late freezing of Ardabil Province for time periods of 2011-2033, 2046-2065 and 2080-2099. Daily minimum temperature was simulated by using GFDLCM2.1 and HACDM3 models under A2 scenario and the statistical exponential small-scale method LARS-WG. Data used in this research includes elements of precipitation, minimum temperature and sundials on daily scale in stations of Parsabad, Ardabil, Meshginshahr, Sarein and Khalkhal in Ardabil Pr...

The case q = 1 is reduced to the integer moments.

Also we introduce the notion of the generalized statisticallycompleteness in non-Archimedean L-fuzzy normed spaces and we show thatthe non-Archimedean L-fuzzy normed space is generalized statistically complete.

The beta generalized Rayleigh distribution provides a rather general and flexible framework for statistical analysis of positive data, which provides a better fit than other statistical models in lifetime data analysis. The expansions of the cumulative distribution function and the probability density function using the moments and the moment generating function in addition, the parameters is approached by the method of maximum likelihood and the observed can be discussed in this thesis. Keywords: Generalized Rayleigh distribution, Moments, Moment generating function, Maximum likelihood function.

We examine the S-T-X family and T-X-Y family of distributions and then extend such families for any number of random variables n X , n = 0, 1, … ,k, as " the transformers " or random variables n T , n = 0, 1, …, k, as " the transformeds". We call such Families of distributions" extended T-X family of first kind (extended T-X (I))" and " extended T-X family of second kind (extended-X (II))", respectively. Some of their properties and special cases are discussed. Several known continuous distributions presented as members of this family.

The obtained transform provided a suitable generalization of the characteristic function of random variables. It was shown that complex fractional moments which are complex moments of order nq th of a certain distribution, are equivalent to Caputa fractional derivation of generalized characteristic function (GCF) in origin, n being a positive integer and 0 < q ≤ 1 . The case q=1 was reduced to the complex moments. Finally, after introducing fractional factorial moments of a positive random variable, we presented the relationship between integer moments, fractional moments (FMs) and fractional factorial moments (FFMs) of a positive random variable.

With this introduction, we obtained a new relationship between discrete fractional calculus and statistics. Also, the fractional versions of the discrete uniform distribution are developed and their statistical properties are discussed.

By this order, in a setup where the sample size is random, having discrete delta and nabla distributions, we obtain some ordering results involving ordinary and fractional order statistics. Some applications in frailty models and reliability are presented as well.

The classical inference includes obtaining the maximum likelihood estimator, an exact confidence interval, and the confidence intervals based on Wald and signed log-likelihood ratio statistics. Bayesian inference includes obtaining Bayes estimator, equi-tailed credible interval, and highest posterior density (HPD) interval given both informative and non-informative prior distributions. Bayes estimator of R is obtained using four methods: Lindley's approximation, Tierney-Kadane method, Monte Carlo integration, and MCMC. Also, we compare the proposed methods by simulation study and provide a real example to illustrate them.
