Our article provides a study on the use and improvement of Hull and White’s (1988) control variate technique in pricing options. It contributes to the literature in two ways. Firstly we show that it is not optimal to use the entire error of a control variate against its known price (usually a closed-form solution) to correct and improve the unknown error of the unknown price of a complex option...

Changes in stock price will be influenced by many aspects of factors. When we are predicting stock price, it is difficult to build a determined mathematical model between stock prices and these complex factors. This paper first utilizes ε − SVM (ε − support vector machine) to build a stock price prediction model. By fitting the prediction error sequence, we find the law factors, which the predi...

klinkenberg permeability is an important parameter in tight gas reservoirs. there are conventional methods for determining it, but these methods depend on core permeability. cores are few in number, but well logs are usually accessible for all wells and provide continuous information. in this regard, regression methods have been used to achieve reliable relations between log readings and klinke...

this paper aims to investigate the role of each aggregate spending component in the monetary policy transmission in indonesia. it assesses the relative strength of the role of each spending component in the monetary policy transmission. in so doing, this study employs the contribution analysis, which is calculated based on the cumulative impulse response of each component of gdp to a monetary p...

this paper, i have focused on the tax side of the fiscal policy to  investigate the past and future behavior of fiscal sustainability in iran. to do so, i have employed two different forward-looking and backward-looking approaches. first, the backward-looking approach is the fiscal policy rule proposed by daving & leeper (2011). precisely, this rule determines that whether the fiscal policy is ...

The Journal of Economic Literature codes classification system (JEL) published by the American Association (AEA) is de facto standard for research literature in economics. JEL used to classify articles, dissertations, books, book reviews, and working papers EconLit, a database maintained AEA. Over time, it has evolved extended with over 850 subclasses. This paper reviews history development sys...

Opportunistic error correction based on fountain codes is especially designed for the MIMOOFDM system. The key point of this new method is the tradeoff between the code rate of error correcting codes and the number of sub-carriers in the channel vector to be discarded. By transmitting one fountain-encoded packet over a single sub-carrier per antenna, the ADC is allowed to only take care of the ...

This study aimed to discover the insight of error correction by implementing two correction systems on three Iranian university students. The three students were invited to write four in-class essays throughout the semester, in which their verb errors and individual-selected errors were corrected using the Code Correction System and the Individual Correction System. At the end of the study, the...
