Abstract. Count data over time are observed in many application areas. Many researchers use time series patterns to analyze this data. In this paper, the poisson count time series linear models and negative binomials on this type of data with the explanatory variables are studied. The Likelihood analysis and the evaluation of count time series model based on generalized linear models are pres...

معمولا در ساختار کواریانس داده های سریهای زمانی مربوط به اقلیم شناسی، آب شناسی، جامعه شناسی، علوم طبیعی، مهندسی برق و علوم اقتصاد و ... رفتار تناوبی مشاهده می شود، از این رواستفاده از سریهای زمانی همبسته متناوب در ده سال گذشته توجه گسترده ای را به خود جلب نموده اند. با توجه به اینکه روشهای آنالیز واریانس اغلب برای مقایسه میانگین های چند جامعه با نمونه های تصادفی هم توزیع و مستقل به کار برده می ...

abstract the present thesis seeks to critically read george orwell’s nineteen eighty-four and animal farm in the light of louis althusser’s thought and theory. the present thesis proceeds to examine and demonstrate althusser’s major concepts including ideological state apparatuses (isas), repressive state apparatuses (rsas), the structure, the subject, and ideological interpellation which r...

chapter one is devoted to a moderate discussion on preliminaries, according to our requirements. chapter two which is based on our work in (24) is devoted introducting weighted semigroups (s, w), and studying some famous function spaces on them, especially the relations between go (s, w) and other function speces are invesigated. in fact this chapter is a complement to (32). one of the main fea...

Fractal analyzing of continuous processes have recently emerged in literatures in various domains. Existence of long memory in many processes including financial time series have been evidenced via different methodologies in many literatures in past decade, which has inspired many recent literatures on quantifying the fractional Brownian motion (fBm) characteristics of financial time series. Th...
