Hopefully, if you have landed on this post you have abasic idea of what theR-Squaredstatistic means. The R-Squared statistic is a number between 0 and 1, or, 0% and 100%, that quantifies the variance explained i

R squared (R2) or coefficient of determination is a statistical measure of the goodness-of-fit in linear regression models. While its value is always between zero and one, a common way of expressing it is in terms of percentage. This involves converting the decimal number into a figure from...

In this post, I show how to interpret regression models that have significant independent variables but a low R-squared. To do this, I’ll compare regression models with low and high R-squared values so you can really grasp the similarities and differences and what it all means. ...

(proportion of variance explained) index. Most pseudo-R-squared statistics are defined as one minus the proportion of variance not explained which is the PVE. So it seems to me that to you would need to square p1 – p0 before you could regard it as a pseudo-R-squared type index ...
