This article considers unbiased prediction of levels when data series are modeled as a random walk with drift and other exogenous factors after taking natural logs. We derive the unique predictors for growth its variance. Derivation level forecasts is more involved because last observation enters conditional expectation highly correlated parameter estimates, even asymptotically. leads to concep...

Using Ordinary Least Square and Quantile regression, this study found a significant positive relationship between lecture and tutorial attendance and marks in a first year quantitative unit-Introduction to Economic Methods (IEM). The results reveal that students who had studied higher level HSC mathematics (with calculus) were better equipped to undertake IEM. In contrast, students who only stu...

the prime objective of the study is to identify the long-run and short-run relationship between indian stock price viz., bse sensex (hereafter named as bse) and gold price (gold) in india. the daily closing price data were collected for the period of ten years ranging from 1st april 2004 to 31st march 2014 with 2490 observations. the study employed two models: model one used gold as dependent v...

Because of the similarities in the algorithm it is quite common to implement division and square root in the same unit. The purpose of this work is to implement a low-power combined radix-4 division and square root floating-point double precision unit and to compare its performance and energy consumption with a radix-4 division only unit. Previous work has been done on reducing the energy dissi...

In this article, we introduce a systematic new method to investigate the conjectural p-adic meromorphic continuation of Professor Bernard Dwork’s unit root zeta function attached to an ordinary family of algebraic varieties defined over a finite field of characteristic p. After his pioneer p-adic investigation of the Weil conjectures on the zeta function of an algebraic variety over a finite fi...
