Adjusted R-squared - Overview, How It Works, Example

WebWhen you have more predictor variables, the R-Squared gets higher (this is offset by the previous point; the lower the ratio of observations to predictor variables, the higher the R-Squared ). If your data is not a simple random sample the R-Squared can be inflated. For example, consider models based on time series data or geographic data.
