Task 2. Multiple Regression and Correlation

20 companies in the region studied the dependence of production output per worker (thous. Rub.) On the introduction of new fixed assets (% of assets at the end of the year) and by the proportion of highly skilled workers in the total number of workers (%)

Required:

• Construct a linear multiple regression model. Record

standardized multiple regression equation. Based

standardized regression coefficients and average coefficients

elasticity to rank the factors according to their impact on the result.

• Find the coefficients of steam, partial and multiple

correlation. Analyze them.

• Find the adjusted coefficient of multiple determination. Compare it with the unadjusted (general) coefficient of determination.

• Use the F-test to assess the statistical reliability of the Fisher regression equation and the coefficient of determination.

• Use the F-test private Fisher assess the feasibility of the inclusion in the equation of multiple regression and factor after factor after.

• Find the equation of linear regression of the pair, leaving only one significant factor.
