Tīmeklis2024. gada 7. jūl. · So R-squared gives the degree of variability in the target variable that is explained by the model or the independent variables. If this value is 0.7, then it means that the independent variables explain 70% of the variation in the target variable. R-squared value always lies between 0 and 1.
