In the theoretical analysis, dependency of variables is stochastic. Consideration of the residual variable within such a model is needed. Other factors that influence the score variable are grouped in the residual. Uni-factorial nonlinear models are linearized transformations that are applied to...

One of the main aspects analyzed in this paper is the quarterly evolution of the seasonally adjusted GDP comparatively with the corresponding quarter of the previous year. As for the impact of foreign investments, year 2012 was a year when a series of sectors of activity kept on getting...

In this paper, the authors propose solving the problematic regarding the estimation of the parameters for the linear regression model. For this, the least squares method, the maximum likelihood method and the Gauss-Markov theorem are used. There are also presented the properties of the...

The emergence of new patterns of conflict with globalization has led to the re-configuration of the security agreement and the emergence of a "new security paradigm" in recent years. Securing could still lead to neglect issues of governance and the creation (or re-creating) the state monopoly of...

The macroeconomic indices analyse shall be studied on goinging development in order to know the manner of actual transformation of these during each particular stage.For an actual analyse of phenomena development over time, it use as study instrument the statistical adjustment series, the...

The analysis of the correlations between the economic variables can be performed depending on non-linear functions also, which are linearized by transformations. We proceed likewise in order to submit the non-linear model in a simple equivalent form, allowing an easy interpretation of the...

In this paper, the research focuses on the evolution of the GDP in recent years. The data are collected from official sources, mainly the publications of the National Institute of Statistics. The research also emphasizes the role of resources and utilizations as factors that determine the...

The economic and financial crisis considered within the national behavior, within the behavior implied by the one involved by the overlapped context, within the mixed and overlapped behavior, both national and international (and vice-versa), proved that each country and the European Union as...

Regression function is the key to making many micro and macroeconomic analysis. After studying logical variables to be analyzed, graphical representation of data series and primary interpretation of information we pass to fundament the econometric model to be used.

This article outlines the authors’ preoccupation for the research of short-term statistics particularities. There are defined: the short-term statistics, the main characteristics of infra-annual statistical researches, the implementation of integrated short-term statistical research, aspects...
