R2 value of 0
WebAn R 2 of 1.0 indicates that the data perfectly fit the linear model. Any R 2 value less than 1.0 indicates that at least some variability in the data cannot be accounted for by the model (e.g., an R 2 of 0.5 indicates that 50% of the variability in the outcome data cannot be explained by the model). View complete answer on ncbi.nlm.nih.gov. WebThe R-squared value, denoted by R 2, is the square of the correlation.
