Sunrise Donuts Sales Data Analysis

Features:
• Data Update: Automatically appends new data to an aggregated file starting from the last recorded date.
• Forecasting: Utilizes Facebook Prophet to predict future trends based on historical data.
• Interactive Visualization: Generates interactive plots using Plotly for exploring and analyzing forecasts.

Notes:
• Weather data was tested as regressors to improve forecasts
• Cross validation back testing alongside hyperparameter tuning resulted in worse RMSE.
• Possible rationale behind these results:
  • The available weather data is not local enough to the business location
  • Using daily weather aggregates is not fully representative of business hours between 4am to 1pm
  • Weather data is not a strong factor in donut sales numbers
