ith this service you can find the following indicators:
multiple regression equation;
matrix of pairwise correlation coefficients;
parameters of multiple regression equations;
average elasticities for the linear regression;
multiple coefficient of determination;
confidence intervals with a probability of 0.95 for the individual and the average resultant variable;
Specify the number of data (number of rows), the number of variablesx pressed Next. The resulting solution is stored in the file MS Word. For editing, you can use formula editor Microsoft Equation If a lot of data, you can paste them from MS Excel. To do this, specify the number of variables x press Insert from Excel.
In studying this topic the focus should be given to the specification of multiple regression model, the selection factors and the choice of form of the equation when building a multiple regression, assessing the reliability of the results of multiple regression and correlation. It is important to study random residues using the linear model, the need for a generalized method of least squares for linear regression models with heteroscedasticity and autocorrelation remains.
study the subject, a student must know the requirements for the factors to be included in a multiple regression model, the problem of multicollinearity factors and ways of its solution, the mathematical formalism of multiple regression and correlation, particularly its use in violation of OLS assumptions, the essence of the algorithm application generalized method of least squares.
A study of the topic the student should acquire the skills of constructing multiple regression model, optimize its structure, quality assessment model and the possibility of its practical use for predicting the test of economic indicators.
