Linear regression model involves the identification of variables for defining specification for variable and model residuals; the context in which the regression model is used. Analysis of chronological (time) using a temporal function which, in essence, is also a regression, with a variable...

The regression function serves as a basis for carrying out the numerous analyzes micro or macroeconomic indicators. Information obtained by use of the model simple linear regression are not always sufficient to characterize changes in an economic phenomenon and, in particular, to identify...

In this paper, the authors present some considerations regarding the use of the multifactorial regression model in the statistical analysis of economical phenomenon. The paper comprises the steps necessary t determine the parameters of the model, the testing of model and the interpretation of...

This study approaches, from the theoretical viewpoint, the multi-factorial regression method as tool in the analysis of links establishing between indicators in economy, the conditions in which all the other factorial variables remain constant. Starting from the reality that the equation of...

The Taylor curve allows the description of the compromise relationship between the variability of the inflation ratio and the dynamics of production, from our study; it can be observed that the value of the inflation quotient decreases with the growth of the weight of production rise. The...

In this paper we have studied the dependence between GDP, final consumption and net investments. To analyze this correlation, the article proposes a multiple regression model, extremely useful tool in economic analysis. Regression model described in the article considers the GDP as outcome...

GDP, one of the main macroeconomic aggregates specific to SNA represents the synthetic expression of economic activity results produced within the economic territory over a period of time, regardless of the contribution that they had domestic or foreign subjects.

In countries like Romania, which was in the process of transition to a market economy, the need to attract investment in areas that are amenable to develop objective is a necessity. Romania, like other Eastern European countries, has inherited an integrated industrial development capacities,...

This article shows the evolution of the main macroeconomic indicators of results, Gross Domestic Product correlated with variation of final consumption in our country in the years 1990 to 2011. The values of the two macroeconomic indicators have been deflated using the consumer price index with...

The evolution of economic phenomena do not evolve as linear trajectories, and trajectories can be nonlinear. Analysis of correlations between economic variables can be done by linear functions which are linearized transformations. Do so for the present nonlinear model into an equivalent simple...
