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...

A linear regression model assumes the identification of the two variables, the knowledge of the models used for the estimation of the two parameters, of the methods used to test the properties of regression model estimators and of the main aspects regarding the use of regression model in...

In this paper, the authors measure, with the help of a multiple regression model, the links between the value of average social insurance pension, as resultant variable, and as factorial variables, gross average salary, annual inflation ratio and the annual evolution of GDP. The model is applied...

In this paper, the authors measure, with the help of a multiple regression model, the links between the value of GDP, as resultant variable, and as factorial variables, the overall value of properties, the value of agricultural terrains, inide terrains and infrastructure. The model is applied...
