I also have this question that I want answered.

1. I looked at the links in the article, but most of them only generally explain what that value is, not detailed algorithms or calculations. Book link I can't read because I don't have enough budget to buy it. Do you have any documentation to help me solve this problem? Thank 😀
2. In the reply, I saw a link to this book that seemed free, but when I accessed it, it couldn't be found " \* Register for free e-Book: [Digital book download: Machine Learning with the Elastic Stack - Second Edition](https://events.elastic.co/machinelearningwithelastic)"

> We are trying to use anomaly detection from Machine Learning. But very little information is available on the internet regarding it. Can you please help us with the following? Details of anomaly detection algorithm, which algorithm is getting used, how does it work etc? Also how is the severity calculated? What are the typical values in the anomalies displayed? Which algorithm gets used for detecting anomalies in univariate time series? Any document throwing light on the above documents will…
