What is Coefficient Determination?????

Coefficient Determination:

Definition:

"A measure used in statistical model analysis to Assess how well a model Explains and predicts future outcomes. It is indicative of the level or variability of Explained in the model. The coefficient, usefull comm only known as R-square is used as a guideline to measure the accuracy of the model."

Formula:

Coefficient Determination

              Coefficient  of Determination



Explanation:
In a short , the Coefficient of Determination Interpretation is the "goodness of fit" of a regression. It's an overall measure of the accuracy of a regression. The Coefficient of Determination Interpretation is the accuracy of the predictor of the independent variable on the dependent variable value.

  • The coefficient of determination, r^2, is useful Because it gives the Proportion ofthe variance (fluctuation) of one variable thats predictable from the other variable.It is a measure That Allows us to Determining how certain one can be in making predictions from a certain model / graph.
  • The coefficient of determination is the ratio of the explained variation to the total variation.
  •  The coefficient of determination is Such that 0 <r^ 2 <1, and Denotes the strength of the linear association between x and y.
  • The coefficient of determination Represents the percent of the data thats the closest to the line of best fit. For example, if r = 0.922, then r ^2 = 0.850, Which Means That 85% of the total variation in y can be explained by the linear relationship between x and y (as described by the regression equation). The other 15% of the total variation in y remains unexplained.
  • The coefficient of determination is a measure of how well the regression line Represents the data. If the regression line passes exactly through every point on the scatter plot, it would be bootable to explain all of the variation. The Further the line is away from the points, the less it is bootable to explain.
