This paper reflects the statistical modeling concerning the resident population in Romania, respectively the total of the romanian population, through by means of the „Least Squares Method”. Any country it develops by increasing of the population, respectively of the workforce, which is a...

Most existing semi-parametric estimation procedures for binary choice models are based on the maximum score, maximum likelihood, or nonlinear least squares principles. These methods have two problems. They are difficult to compute and they may result in multiple local optima because they require...

The paper uses paired comparison-based scoring procedures for ranking the participants of a Swiss system chess team tournament. We present the main challenges of ranking in Swiss system, the features of individual and team competitions as well as the failures of official lexicographical orders....

Trend determination of underground economy with Schneider model in Romania with analytical methods requires least squares method. Comparing the results of the absolute deviations between empirical and theoretical values for the linear, curvilinear and modified exponential regression, will choose...

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...

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...
