1. What is the difference between R2 and adjusted R2? R2 is a statistic that will give some information about the goodness of fit of a model. In regression‚ the R2 coefficient of determination is a statistical measure of how well the regression line approximates the real data points. An R2 of 1.0 indicates that the regression line perfectly fits the data. Adjusted R2 is a modification of R2 that adjusts for the number of explanatory terms in a model. Unlike R2‚ the adjusted R2 increases only if
