Complex Time Series Decomposition Toolkit

time series decomposition forecasting statistical analysis
Prompt
Develop an Excel-based time series analysis toolkit that performs advanced decomposition of complex datasets. The tool must separate seasonal, trend, and random components using statistical methods, implement multiple smoothing techniques (Holt-Winters, exponential), and generate predictive models with error margin calculations. Create an interactive dashboard that allows users to explore different decomposition methods and forecast scenarios.
