The task of finding anomalies in data when implementing predictive analytics systems. Predictive analytics have become very popular over the past few years. It helps banks approve loans or identify suspicious account activity, email providers filter spam, and retailers predict the likelihood of buying to attract customers. But predictive analytics is quite complex, and therefore its implementation is also fraught with difficulties. When companies take the traditional approach to predictive analytics (that is, treat it like any other type of analytics), they often face obstacles. This is why this area needs tools to detect anomalies in the data. These tools should help to identify outstanding values in order to draw dependencies with the factors of their occurrence and identify them in the future. This article describes a package in the R language that is anomalies in multidimensional time series. This package is capable of detecting anomalies using three different methods: the n-sigma method, the CUSUM method, and the 4th order central moment method. Also, this package searches for complex anomalies, which are a direct indicator of errors in the system due to the fact that anomalies are found in multidimensional data.
