How to Calculate R-Squared without Lopping Through DataFrames and Understand Its Implications on Model Accuracy.
Understanding R-Squared and the Problem with Lopping Through a DataFrame R-squared, often abbreviated as R² or r², is a statistical measure that represents the proportion of the variance for a dependent variable that’s explained by an independent variable. In simpler terms, it measures how well a linear regression model fits the data. Given this context, the question at hand revolves around calculating the R-squared value for increasingly larger numbers of rows in a dataframe using Python and the scikit-learn library.
