R Squared & Coefficient of Determination Theory - ML with Python - Part - 9
In this video, we will talk about R Squared & Coefficient of Determination Theory.
What is R Squared?
R-squared (R2) is a statistical measure representing the proportion of the variance for a dependent variable explained by an independent variable or variables in a regression model.
Why is R Squared used?
R Squared is used to determine how good fit a model is.
What is the coefficient of determination in linear regression?
The coefficient of determination is the square of the correlation(r), thus it ranges from 0 to 1. With linear regression, the coefficient of determination equals the square of the correlation between the x and y variables.
