Sorted by: 6. McFadden's pseudo- R 2 is consistent with the log-likelihood model we optimise in logistic regression. The ordinary R 2 is consistent with the log-likelihood model for the linear regression. In linear regression, we maximise the log-likelihood: − ∑ i ( y i − β x i) 2. Compare this with the definition of R 2:

In general, the greater the Cohen’s d, the larger the effect size. For Pearson’s r, the closer the value is to 0, the smaller the effect size. A value closer to -1 or 1 indicates a higher effect size.
