Explanation

Key Features

  • Data Preprocessing: Cleans and prepares data for modeling.
  • Model Training: Uses linear regression for prediction.
  • Forecasting: Predicts future values based on input data.
  • Error Handling: Validates inputs and manages exceptions.
  • CLI Interface: Interactive command-line usage.

            elif cmd.startswith('predict'):
                parts = cmd.split()
                # ... 12 more lines in the file ...
                y = np.loadtxt(parts[2], delimiter=',')
                analytics.plot(X, y)
            elif cmd == 'exit':
