The numeric expr represents the Y value for the trend and the series (time columns) represent the X value. Cluster : Collects a set of records into groups based on one or more input expressions using K-Means or Hierarchical Clustering. Outlier : This function classifies a record as Outlier based on one or more input expressions using K-Means or Hierarchical Clustering or Multi-Variate Outlier detection Algorithms. Regr : Fits a linear model and returns the fitted val

In this post I'm focusing on available Advanced Analytics function that are "out-of-the-box
