ARMA Time Series Analysis

Introduction

ARMA (Autoregressive Moving Average) analysis is a powerful time series forecasting model used across hydrology, meteorology, and environmental science. Traditional ARMA modeling in Excel requires NumXL for model construction, parameter calibration, and forecasting. The three-part model includes parameters, goodness of fit, and residuals diagnosis.

Sourcetable offers an AI-powered alternative that eliminates the need for Excel expertise in ARMA analysis. This innovative platform lets you interact with an AI chatbot to analyze your data, create visualizations, and generate insights. Simply upload your time series data or connect your database, then tell the AI what analysis you need. Sourcetable maintains ARMA's benefits of fast construction, low data requirements, and standardized processes while making complex analysis accessible through natural language.
