It selects the model that yields the\nhighest adjusted R-squared (by default) or R-squared, depending\non user preference. In model evaluation, both R-squared and\nadjusted R-squared are key metrics: R-squared measures the\nproportion of variance explained but tends to increase with the\naddition of predictors—regardless of relevance—potentially\nleading to overfitting. Adjusted R-squared compensates for this\nby penalizing model complexity, providing a more balanced view\nof fit quality. The goal of olr is to identify the most\nsuitable model that captures the underlying structure of the\ndata while avoiding unnecessary complexity. By comparing both\nmetrics, it offers a robust evaluation framework that balances\npredictive power with model parsimony. Example Analogy: Imagine\na gardener trying to understand what influences plant growth\n(the dependent variable). They might consider variables like\nsunlight, watering frequency, soil type, and nutrients\n(independent variables). Instead of manually guessing which\ncombination works best, the olr function automatically tests\nevery possible combination of predictors and identifies the\nmost effective model—based on either the highest R-squared or\nadjusted R-squared value. This saves the user from\ntrial-and-error modeling and highlights only the most\nmeaningful variables for explaining the outcome.
