Time series forecasting is a critical technique for analyzing data points collected over time. This tutorial will guide you through the fundamentals, tools, and applications of time series analysis.
What is Time Series Forecasting?
Time series forecasting involves using historical data to predict future values. It's widely applied in finance, weather prediction, stock markets, and more.
Key Concepts
- Trend: Long-term movement in data (📈)
- Seasonality: Regular patterns repeating over fixed periods (🔁)
- Noise: Random fluctuations in the data (🌪️)
Common Methods
ARIMA (AutoRegressive Integrated Moving Average)
- Best for linear trends and seasonal patterns
- Example: Forecasting monthly sales data
LSTM (Long Short-Term Memory)
- A type of neural network for capturing complex non-linear relationships
- Example: Predicting stock prices
Prophet by Facebook
- Designed for robust forecasting with seasonality and holidays
- Example: Predicting website traffic
Practical Applications
