Predictive Grouping is an approach that allows users to assess and create the appropriate number of clusters (groups) for their data to be assigned based on their similarity to each other in the same cluster and dissimilar to other data assigned to other clusters. K-Centroids represent a class of algorithms for doing what is known as partitioning cluster analysis. These methods work by taking the records in a database and dividing (partitioning) them into the best K groups based on some criteria. The purpose of creating clusters is to assist you in the business decision-making process as it relates to the clustered data.
Clustering could apply to stores, customers, vendors, products or all of the above. All of the variables selected for your cluster analysis must be numerical.
The following is a high-level description of the K-Centroids Tools used for Predictive Grouping:
Alteryx Predictive analytic tools are built on Open source R. Alteryx users are not required to know R to execute predictive models because all of the models in Alteryx are packaged into easy-to-use macro tools that only require configuration. All predictive tools are macros, and therefore not a black box. Macros provide the user with the flexibipty to open all models and dissect the logic, as well as see and modify the R-script(s) being executed. This video provides a brief tutorial of using Predictive Grouping tools on retail store metrics and surrounding demographics.
The following tools aredemonstrated: K-Centroids Diagnostics, K-Centroids Analysis, Append Cluster
In my tool palate, I don't see predictive grouping tools. How do I install it? Should I install R first? Please help.
First, make sure they're not just hiding. Click the + button at the far right end of your tool categories and make sure the Predictive Grouping category is enabled. If you don't see it there, you need to install the predictive tools. Go to downloads.alteryx.com and click Alteryx Designer. Find and click the version of Designer you're using, either the current release under the New Versions tab or an older version under the Previous Versions tab. Then download and install the Alteryx Predictive Tools, either the Admin or Non-Admin version, depending on what type of Designer you have installed.
