We study the problem of parameter estimation for Ornstein–Uhlenbeck processes driven by symmetric α-stable motions, based on discrete observations. A least squares estimator is obtained by minimizing a contrast function based on the integral form of the process. Let h be the length of time...

This paper proposes a generalized model to estimate the peak hour origin–destination (OD) traffic demand variation from day-to-day hourly traffic counts throughout the whole year. Different from the conventional OD estimation methods, the proposed modeling approach aims to estimate not only...

A data-driven approach to the performance analysis of wind turbines is presented. Turbine performance is captured with a power curve. The power curves are constructed using historical wind turbine data. Three power curve models are developed, one by the least squares method and the other by the...

In this research we can to observe the statistical modeling concerning the Life Expectancy in Romania, between 2000-2013, through by means of the „Least Squares Method”. The Life Expectancy reflects the average duration of the life concerning a person in a certain country analysed. The Life...

Local government units (LGU) are nowadays facing the very difficult and complicated task of making reasonable decisions regarding the transforming of SPZOZs into capital companies. First, it seems necessary to carry out a simulation of costs and advantages of the assumed models and solutions...

The implementation of primary functions of local development management, especially its planning, organizing and controlling, cannot leave aside the financial aspects of these processes1. This can be attributed to the fact that every decision taken in the commune concerning strategic or...

We propose a coherent unified approach to the study of the linkages among economic growth, financial structure, and inequality, bringing together disparate theoretical and empirical literature. That is, we show how to conduct model-based quantitative research on transitional paths. With...

Do tax incentives for science and technology stimulate additional investment? We use detailed data on applications and acceptances for R&D tax incentives, a special survey, and for the first time, the science and technology module from the 2000-2002 Survey of Manufacturers database in Colombia...
