Interpreting adjusted r squared value

WebIt’s nice to know method to correctly deuter coefficients for log-transformed data, but it’s critical to know what exactly respective model is implying when it includes log-transformed data. To get a better understanding, let’s use R to simulate some data that will require log-transformations to a real analysis. WebNov 13, 2024 · The adjusted R-squared is a modified version of R-squared that adjusts for the number of predictors in a regression model. It is calculated as: Adjusted R2 = 1 – [ (1-R2)* (n-1)/ (n-k-1)] where: R2: The R2 of the model. n: The number of observations. k: The number of predictor variables. Because R2 always increases as you add more predictors ...
