One of the main tasks to analyze and design a mining system is predicting the behavior exhibited by prices in the future. In this paper, the applications of different prediction methods are evaluated in econometrics and financial management fields, such as ARIMA, TGARCH, and stochastic differential equations, for the time-series of monthly copper prices. Moreover, the performance of these metho...

this research studies the application of hybrid algorithms for predicting the prices of crude oil. brent crude oil price data and hybrid intelligent algorithm (time delay neural network, probabilistic neural network, and fuzzy logic) were used to build intelligent decision support systems for predicting crude oil prices. the proposed model was able to predict future crude oil prices from august...

agricultural prices have a high fluctuation and forecasting may help decision making effectively. the aim of this study was to forecast the nominal and real prices of sugar beet and to recognize the appropriate forecasting model. initially the stationary of the series was tested. in order to investigate whether the series are stochastic, the nonparametric test of vald-wulfowitz and parametric t...

This paper analyzes determinants of ex-manufacturer prices for originator and generic drugs across countries. We focus on drugs to treat HIV/AIDS, TB, and malaria in middle and low-income countries (MLICs), with robustness checks to other therapeutic categories and the full income range of countries. We examine the effects of per capita income, income dispersion, competition from originator and...

We conjecture that systematic trends in errors can help detect patterns in restaurant prices. For example, if errors correlate with geography, we may identify regions with higheror lower-than-expected prices. To test this for New York, we retrained our price range predictor using the entirety of New York as the test set, Philadelphia as the dev set, and the remaining cities as training data. We...

Bu çalışmada ÜFE ve TÜFE arasında nedensellik eşbütünleşme ilişki 2005-2021 yılları aylık veriler kullanarak Türkiye özelinde incelenmiştir. amaçla ARDL sınır testi, Granger testi Toda-Yamamoto yöntemleri kullanılmıştır. Analiz sonuçlarına göre, oldukça güçlü bir ilişkisi vardır seriler birlikte hareket etmektedir. Öyle ki, uzun dönemde ÜFE’de meydana gelen %1’lik artışın TÜFE’de yaklaşık %1.1 ...
