[edit] Introduction
- This page contains content of Extension Nodes for SAS Enterprise Miner that are created by Gerhard Svolba.
- Extension nodes for are a powerful tool to enhance the functionality of SAS Enterprise Miner.
- At this page you will find two groups of extension nodes
- Extension Nodes for Data Preparation for Analytics which are based on the book with the same name
- Various extension nodes that I frequently use in SAS Enterprise Miner (GTOOLS)
[edit] Downloads
- Download the ZIP-File that contains the extension nodes (XML-File, GIF-File, SAS Catalog). Additionally the ZIP file contains
- two example EM-Diagrams. These diagrams can be imported into SAS Enterprise Miner in order to see an example with the extension nodes.
- the SAS datasets USAGE and ACCOUNTS
- Download a paper that describes the use of extension nodes for data preparation for analytics
- Download a paper that describes the use of the GTOOLS
- Comments and suggestions can be sent to the author.
[edit] Extension Nodes for Data Preparation for Analytics
- Based the book Data Preparation for Analytics five node are supplied that allow to pre-process transactional data.
- Each node outputs the data in a one-row-per-subject data structure so that the data can be used for data mining
- The following nodes are available
- Trend Regression: Calculates derived variables that describe the trend of an interval variable in up to two time intervals and creates a concatenated group variable
- Correlation: Calculates derived variables that describe the correlation of values with its overall mean per timeid or with other input variables
- Concentration: Calculates derived variables that describe the concentration of an interval variable in a sub-hierachy of the analysis subject
- Category Count: Calculates derived variables for categorical data. Aggregations like counts, distinct counts or proportions are calculated
- Transpose from LONG to WIDE: Transpose a dataset from a multiple-row-per-subject structure into a one-row-per-subject structure
[edit] Various Extension Nodes - GTOOLS
- These nodes are a collection of SAS Enterprise Miner Tools that I frequently use, as they seem helpful for me:
- Target BarChart: Displays the relationship between an input variable and the target variables in a bar chart
- Item-Relationship-Map: Displays the 2-way association rules in a hierarchical tree structure.
- Anonymous Node: Removes the id variable of a subject from the table and stores it in a separate table. Optionally creates a surrogate key. This node shall be used if a dataset shall be made anonymous.
- EM DataSource Copy: This node is not yet finished! I will copy to metadata of an existing data source in SAS Enterprise Miner.
[edit] Download
- Read a paper describing Gerhard Svolba's extension nodes
- Download the files to install Gerhard's extension nodes
- Download a SAS Enterprise Miner 5.3 demo project to see how the nodes can be used
[edit] Links
- Comments and suggestions can be sent to the author.
- Navigate to content of Data Preparation for Analytics or find other samples under Gerhard's Samples
- Read the Enterprise Miner 5.3 Extension Nodes: Developer's Guide
- Basically you need only 3 things to create an extension node
- A SAS macro that defines the functionaliy
- A XML files that defines the node parameters and the code location
- An icon (16-Bit and 32-Bit) to display the icon in the toolbar and in the EM-Diagram.
- Read the SAS Global Forum 2008 Paper from Sascha Schubert Tailoring the use of SAS® Enterprise Miner®
