Seaborn KDE Plot: Comparing Returns with and Without Feature_1

This code utilizes the kdeplot function from the Seaborn library to generate two density curves. The first curve represents the distribution of returns for the sample set containing the Feature_1 feature, while the second curve represents the distribution of returns for the sample set excluding Feature_1. The 'data' parameter specifies the data source for each sample set, 'linestyle' defines the line style of the curves, and 'label' sets the label for each curve.

Specifically, the second curve in this code uses the 'alpha' parameter to set the transparency to 0.7, allowing the two curves to overlap while maintaining their individual characteristics. Finally, the title is set to 'KDE of Returns from data with and without Feature_1', and labels for both curves are added to the legend.
