What is an unbiased estimate of population R-square?

WebThis equation can either be seen in a dialogue box and/or shown on your graph. How well this equation describes the data (the 'fit'), is expressed as a correlation coefficient, R 2 (R-squared). The closer R 2 is to 1.00, the better the fit. This too can be calculated and displayed in the graph. WebFor these models, R-squared indicates the proportion of the variability in the dependent variable that is explained by model. That is, an R-squared of 0.60 indicates that 60% of the variability in the dependent variable is explained by the model. Pseudo R-squared. For many types of models, R-squared is not defined.
