Using R, the author fits a linear model achieving 97% R-squared, calculates LOO RMSE showing typical prediction error under 3%, identifies mild systematic bias at extremes of the scale, and resolves it by adding a quadratic term. An ANOVA test confirms the WGI's predictive relationship with WJP scores is stable over time (p=9%), concluding the WGI is a reliable proxy for WJP levels when non-linearity is accounted for. ## Full article daily.dev links to this article rather than hosting it.
