Economic models are often used to study a single decision or outcome. The outcome variable may be fully observed, continuous, and unrestricted (for example, log consumption); fully observed and continuous but restricted to an interval (fraction of expenditure devoted to a certain category of goods); continuous but censored (earnings subject to known withholding limits for social insurance); a m...

Financial Econometrics is simply the application of econometric tools to financial data. For many years, least squares techniques provided satisfactory tools. Stock market forecasts, efficient market tests, and even tests of portfolio models such as the CAPM and APT were essentially implemented with least squares on cleverly manipulated data sets. More recently, however, the field has developed...

evaluation of river discharges trends is very important for water resources management and design of irrigation and drainage networks. in this research, annual, seasonal and monthly trends of maroon river discharge were evaluated using the mann-kendall and sen’s slope estimator non-parametric tests and the regression analysis parametric test. for this purpose, river discharge data from five h...

Synthetic Aperture Radar (SAR) is the only way to evaluate deformation of the Earth’s surface from space on the order of centimeters and millimeters due to its coherent nature and short wavelengths. Hence, by this means the long term risk monitoring and security are performed as precisely as possible. Traditional SAR imaging delivers a projection of the 3-D object to the two dimensional (2-D) a...

Behavioral econometrics is one part of a methodological trinity that includes theory, data collection and econometrics. Sometimes, on a good methodological day, there are few demands on the econometrician and the data can just be described and summarized, or elementary statistical tests applied. More often, latent structures from theory have to be estimated, and data collection has to be design...

Two of the fastest growing frontiers in econometrics and quantitative finance are time series and financial econometrics. Significant theoretical contributions to financial econometrics have been made by experts in statistics, econometrics, mathematics, and time series analysis. The purpose of this special issue of the journal on “Frontiers in Time Series and Financial Econometrics” is to highl...
