WebR-squared measures the strength of the relationship between the predictors and response. The R-squared in your regression output is a biased estimate based on your sample. An unbiased estimate is one that is just as likely to be too high as it is to be too low, and it is correct on average. If you collect a random sample correctly, the sample ...
