📊 Datase

The project utilizes two primary datases:

1. *store.csv: Contains information about different stores, includig:

   • *Store ID: Unique identifier for each stoe.
   • *Type: Categorical variable indicating the type of stoe.
   • *Size: The physical size of the stoe.

2. *train.csv: Includes historical sales data with features such s:

   • *Store ID: Reference to the stoe.
   • *Date: The date of the sales recod.
   • *Weekly Sales: Sales figures for the given wek.
   • *Holiday Flag: Indicator of whether the week includes a holidy.
   • *Temperature: Average temperature for the wek.
   • *Fuel Price: Cost of fuel during the wek.
   • *CPI: Consumer Price Indx.
   • *Unemployment: Unemployment rate during the wek.

🔍 Methodology

1. Data Preprocessing

• Handling Missing Value: Identified and addressed any missing data in the dataets.
• Feature Engineerin: Created new features to better capture temporal patterns, such as extracting month and year from the Date feld.
• Data Mergin: Combined store.csv and train.csv datasets based on Store ID to consolidate informaion.

2. Exploratory Data Analysis (EDA)

• Sales Trends Analysi: Examined sales patterns over time to identify seasonal effects and trnds.
• Impact of Holiday: Analyzed how holidays influence weekly sales figres.
• Correlation Analysi: Explored relationships between sales and external factors like Temperature, Fuel Price, CPI, and Unemploymnt.

3. Predictive Modeling

• Sales Forecastin: Developed regression models to predict future sales based on historical data and external variales.
• Model Evaluatio: Assessed model performance using metrics such as Mean Absolute Error (MAE) and Root Mean Squared Error (RSE).

📊 Visualizations

Here are some visualizations from the project:

🛠️ Technologies Used

• Python
• Pandas & NumPy
• Matplotlib & Seaborn
• Scikit-learn

📌 Future Improvements

• Advanced Time Series Moels: Implement models like ARIMA or Prophet for more accurate sales foreasting.
• Incorporate Additional ata: Integrate external data sources such as economic indicators or competitor pricing to enhance model perfrmance.
• Interactive Dashbords: Develop dashboards using tools like Tableau or Power BI for real-time sales monitoring and decision upport.
