Python Libraries for Time-Series Forecasting

 Several Python libraries excel at time series forecasting, each with its own strengths and weaknesses. Here are some of the most popular options:

1. Prophet:

  • Focus: Univariate time series forecasting.
  • Strengths: Easy to use, good for seasonal and trend forecasting, interpretable results.
  • Weaknesses: Limited to univariate forecasting, not suitable for complex models.
  • Libraries: Prophet (standalone package).

2. Darts:

  • Focus: General-purpose time series forecasting.
  • Strengths: Wide range of forecasting models (ARIMA, ETS, Prophet, LSTMs), flexible and customizable.
  • Weaknesses: Can be complex to get started with, requires more knowledge of forecasting techniques.
  • Libraries: Darts.

3. Sktime:

  • Focus: Time series analysis and forecasting.
  • Strengths: Comprehensive set of tools for time series analysis, integrates with other scikit-learn libraries.
  • Weaknesses: Not as user-friendly as Prophet or Darts, requires some background in statistics and machine learning.
  • Libraries: scikit-learn, statsmodels.

4. AutoTS:

  • Focus: Automated time series forecasting.
  • Strengths: automatically tries different algorithms and selects the best one for your data.
  • Weaknesses: Less flexibility and control over model selection, might not work well for all types of problems.
  • Libraries: AutoTS.

5. Greykite:

  • Focus: Probabilistic time series forecasting.
  • Strengths: Provides uncertainty estimates for predictions, good for handling missing data and outliers.
  • Weaknesses: Can be computationally expensive, not as widely used as other libraries.
  • Libraries: Greykite.

Additional libraries:

  • pmdarima: Specifically designed for ARIMA models.
  • PyCaret: Machine learning wrapper offering various forecasting models.
  • Kats: Scalable forecasting library for large datasets.
  • Tsfresh: Feature extraction for time series data.

Choosing the right library depends on various factors:

  • Forecasting task: Univariate vs. multivariate, forecasting horizon, specific needs like seasonality or trend detection.
  • Data characteristics: Size, complexity, presence of missing data or outliers.
  • Technical expertise: Some libraries are easier to use than others.
  • Performance requirements: Accuracy, speed, interpretability.
