Bug Report for pyAB Library

Describe the bug

The pyAB library's function conduct_experiment throws an IndexError when trying to generate uplift distribution plots. The error message states, "List index out of range."

To Reproduce

Steps to reproduce the behavior on Google Colab:

1. Navigate to Google Colab Notebook.
2. Run all cells leading to the conduct_experiment function call.
3. Execute the cell containing:

   ad_experiment_bayesian.conduct_experiment(success_null=100, trials_null=1000,
                                             success_alt=125, trials_alt=1000,
                                             uplift_method='uplift_ratio', num_simulations=1000)

4. Observe the IndexError in the output.

Expected Behavior

Expected the conduct_experiment function to complete successfully and display the uplift distribution plots without errors.

Desktop:

• OS: Any (Reproducible on Google Colab)

Additional Context

• The library also throws a FutureWarning regarding the depreciation of the shade parameter in favor of fill in seaborn.
• The error emanates from the line: kde_x, kde_y = ax.lines[0].get_data().
