Time Series Forecasting: A Comparative Analysis of SARIMAX and XGBoost Algorithms

SARIMAX (Seasonal Autoregressive Integrated Moving Average with Exogenous Variables) and XGBoost are both popular algorithms used for time series forecasting, but they have different strengths and weaknesses. Here are the advantages and disadvantages of each algorithm:

Advantages of SARIMAX:
1. Interpretable: SARIMAX models have a well-defined mathematical framework, making them easier to interpret and understand. The model parameters represent the relationships between the past observations and future predictions.

2. Incorporates Seasonality: SARIMAX models can handle time series data with seasonal patterns by including seasonal components in the model. This makes them suitable for forecasting data with recurring patterns.

3. Limited Training Data: SARIMAX can work well with small to moderate-sized datasets, as it primarily relies on past observations and their lags. It does not require a large amount of training data to make accurate predictions.

Disadvantages of SARIMAX:
1. Complex Parameter Selection: SARIMAX models involve selecting appropriate orders (p, d, q) and seasonal orders (P, D, Q, S) based on the characteristics of the data. This process can be challenging and time-consuming, requiring…
