Taking into account the fact that all
factor variables have different dimensions,
correlation-regression modeling should
be based on the logarithm of some of the
presented indicators [19] (
Table 3
). In this case,
the model can be described by the equation
given in formula (2):

coefficients of correlation-regression
modeling of changes in the GDP of the
Russian Federation.
Now we should move on to direct analysis
of the parameters using a correlation model
that allows us to see the strength of the
relationship between the selected parameters
(
Table 3
).
Comparing the values of the parameters
obtained in the course of the study in the
correlation model with the Chaddock scale
4
(
Table 4
), one can see a fairly high strength
of the relationship between the GDP of
the Russian Federation and the volume of
mastered technology in industrial production.
In addition, there is a high strength of the
relationship between the GDP of the Russian
Federation and other factor variables: the
number of industrial companies that have
invested their own funds in R&D programs,

To assess the correlation coefficients or determine the
statistical dependencies of quantitative indicators, the
Chaddock scale is widely used when building multifactor
regression models. The Chaddock scale is popular in
economic, sociological, medical and marketing research. It was
introduced in 1925 by the American scientist Robert Chaddock.
This scale became the first tool for analyzing the strength of
the relationship between indicators.
the average number of employees of
companies functioning in industrial sectors
and the implementation of technological
innovation projects, the share of innovative
goods, works, services in general volume of
shipped industrial products.
Equally, a significant relationship between
the GDP of the Russian Federation as an
indicator of the effectiveness of the developed
model of financial incentives for innovation
projects in industry and the parameters
characterizing the implementation of R&D
and the introduction of technological
innovations indicates that in the future we can
expect an increase in the share of innovative
goods in the total volume of shipped products.
In addition, there is a weak relationship
between the GDP of the Russian Federation
and the volume of foreign financing of
innovation projects in the industry. At the
same time, it should be noted that the share
of foreign investments in the innovation
activities of companies is very low (in the
structure, the indicator did not reach 1%)
