Significance of Adjusted R2
Adjusted R2, a statistical measure, reveals the variance proportion in a dependent variable explained by independent variables within a model. This adjustment accounts for the number of variables, preventing inflation of the R2 value when irrelevant variables are added. It helps determine the true explanatory power of a regression model.

The concept of Adjusted R2 in scientific sources
Adjusted R2 is a statistical measure indicating the variance proportion in a dependent variable explained by independent variables, adjusted for the number of variables in the model.
From: Sustainability Journal (MDPI)
(1) It is a statistical measure that indicates the proportion of variance in the dependent variable explained by the independent variables, adjusted for the number of predictors.[1] (2) A statistical measure that indicates the proportion of variance in the dependent variable that is explained by the independent variables, adjusted for the number of variables in the model.[2]
From: International Journal of Environmental Research and Public Health (MDPI)
(1) Adjusted R2 is a modified version of R-squared that adjusts for the number of predictors in a regression model, providing a more accurate measure of the variance explained by the model.[3]
