Interpreting r squared value for regression
WebMay 30, 2013 · The definition of R-squared is fairly straight-forward; it is the percentage of the response variable variation that is explained by a linear model. Or: R-squared = Explained variation / Total variation. R-squared is always between 0 and 100%: 0% … WebIn each regression, they estimate heterogeneous treatment effects of their three treatments with respect to seven different covariates, which are listed at the top of each column. Each of the seven regressions estimate how the effect of each of the three treatments on water usage varies with respect to one covariate. We will focus on Column 4.
