## [Overview] LLM-Forecast: A New Hybrid Forecasting Method Combining ARIMA and Large Language Models

# LLM-Forecast: A New Hybrid Forecasting Method Combining ARIMA and Large Language Models

LLM-Forecast is an open-source forecasting tool developed by emagod. Its core is a hybrid forecasting methodology that combines the statistical rigor of ARIMA with the semantic understanding capabilities of large language models to achieve more accurate and robust prediction results. It is designed for business analysts, data scientists, researchers, and enterprise decision-makers, providing a user-friendly interactive interface and flexible data export functions.

## [Background] Evolution and Integration Needs of Time Series Forecasting Methods

## Background: Evolution and Integration of Forecasting Methods

Time series forecasting has undergone multiple rounds of innovation, from traditional ARIMA and exponential smoothing to deep learning models (LSTM, Transformer), and then to the exploration of LLMs. Limitations of each method:
- Traditional statistical models (e.g., ARIMA): Solid theory and strong interpretability, but difficult to capture complex patterns and nonlinear relationships
- Deep learning models: Strong pattern recognition, but require large amounts of data and have poor interpretability
- LLMs: Strong semantic understanding and reasoning capabilities, but lack precision in numerical calculations

Combining their advantages has become an important research direction in the forecasting field.
