We’ve discussed the math behind R-squared and implemented it in Python. We’ve practically seen why adjusted R-squared is a more reliable measure of goodness of fit in multiple regression problems. We’ve discussed the way to interpret R-squared and found out the way to detect overfitting ...
In CPython, the global interpreter lock, or GIL, is a mutex that prevents multiple native threads from executing Python bytecodes at once. This lock is necessary mainly because CPython’s memory management is not thread-safe. (However, since the GIL exists, other features have grown to depe...
My naive guess would be whoever implemented it saw the log and needed to ensure the log was not of a negative number. I'm surprised it was never an issue before I agree with this. After verifying the non-negative condition, both functions feed y_pred and y_true into numpy.log1p instea...

Adjusted R-Squared Explained - Learn about Adjusted R-Squared, a crucial statistical measure that adjusts the R-Squared value based on the number of predictors in a regression model. Understand its importance in model evaluation.
given the number of features, it makes for difficult reading when you construct a pairplot of the entire dataset, but the most interesting scatter plots are provided below. The main takeaways are that most of the data appears quite skewed (in the sample) and there are general positive pair...
