What is a Coefficient of Determination?

The determination is also called the determination coefficient, determination coefficient, and determination index. Similar to the complex correlation coefficient, a numerical characteristic that indicates the relationship between a random variable and multiple random variables. It is a statistical indicator used to reflect the reliability of the change of the dependent variable by the regression model. It is generally represented by the symbol R and can be defined as The ratio of the variation of the independent variable to the total variation of the independent variable described by all independent variables in the model.

What is the appropriate decision coefficient?

There is no uniform, clear cut-off value;

If

Difference between judgment coefficient and correlation coefficient

* Judgment coefficient * Correlation coefficient

As far as the model is concerned with two variables
