Practical Time Series Analysis - Aileen Nielsen... May 2026

: Traditional models like ARIMA and Exponential Smoothing are presented as robust baselines, especially for smaller datasets where complex models might overfit.

Aileen Nielsen’s Practical Time Series Analysis stands out as a multidisciplinary guide that fills a significant void in modern data science literature. While many textbooks focus strictly on classical econometrics or purely on deep learning, Nielsen offers a comprehensive pipeline that integrates both worlds for real-world applications like healthcare, finance, and the Internet of Things (IoT).
