SPSS CLEM is the control Language for Expression Manipulation, which is used to build expressions within SPSS Modeler streams. CLEM is actually used in a number of SPSS “nodes” (among these are the Select and Derive nodes) and you can check the product documentation to see the extended list. CLEM expressions are constructed from: Values, […]

Sampling Your Data
Another interesting feature of SPSS Modeler is its built-in ability to sample data. It is pretty typical to have (in one or more files) hundreds of thousands of records to process, and using complete sets of data during testing can take a huge amount of your time and is inefficient in terms of computer processing […]
TM1 vs. SPSS Modeler Comparison Continues – Setting to Flags
Consider the scenario where you have to convert information held in a “categorical field” into a “collection of flag fields” – found in a transactional source. For example, suppose you have a file of transactions that includes (among other fields) a customer identifier (“who”) and a product identifier (“what”). This file of transactional data indicates […]
IBM SPSS Modeler and Duplicate Data
Transactional datasets (especially those originating from databases) may contain duplicate records that must be removed before any modeling can begin. There are simply two situations where duplicate records occur are: Datasets ARE erroneous (causing the same record to multiple times) Datasets ARE NOT erroneous (but records appear multiple times because information is collected different moments […]
Missing Data – “Nothing from nothing” – leaves something?
In TM1, missing data usually means that there is a defect in the logic of your ETL script or you need to check your SQL. In SPSS Modeler, missing values arise for a variety of reasons and they must be considered carefully. You might expect that missing values imply errors or should those records be […]
Data Indiscretions
Data loaded into a TM1 or SPSS model will, in most cases, include files consisting of thousands (or hundreds of thousands) of records. It is not reasonable, given the number of fields and records in files of this size, for you to visually inspect all fields in every record (of every file) for missing or […]
Primary Practices for Examining Data
SPSS Data Audit Node Once data is imported into SPSS Modeler, the next step is to explore the data and to become “thoroughly acquainted” with its characteristics. Most (if not all) data will contain problems or errors such as missing information and/or invalid values. Before any real work can be done using […]
Data Consumption – Cognos TM1 vs. SPSS Modeler
In TM1, you may be used to “integer or string”, in SPSS Modeler, data gets much more interesting. In fact, you will need to be familiar with a concept known as “Field Measurement Level” and the practice of “Data Instantiation”. In TM1, data is transformed by aggregation, multiplication or division, concatenation or translation, and so […]
Importing Data into SPSS Modeler for the TM1 Developer
If you have a TM1 background it is a quick step to using SPSS Modeler -if you look for similarities in how the tools handle certain tasks like, for example, importing data. With TM1, source data is transformed and loaded into cube structures for consolidation, modeling and reporting using its ETL tool TurboIntegrator. In SPSS […]
Exposing TM1 Top
So what is TM1 TOP? Definition and Access The TM1 Top utility empowers you to dynamically monitor “threads” running in an instance of a Cognos TM1 server. TM1 Threads are of three possible “types”: User Threads – Name of an actual user that is logged into TM1 Chore Threads – A chore running on the […]
Data Mining with IBM SPSS Modeler v15
Having recently completed the course “IBM SPSS Modeler & Data Mining” offered by Global Knowledge, I was looking to find more opportunities to do some modeling with SPSS Modeler. So, when I read in the news recently, about college recruiters using predictive techniques to determine the probability of a particular recruit graduating on time, I […]
Three Attributes of an Agile BI System
In an earlier blog post I wrote that Agile BI was much more than just applying agile SDLC processes to traditional BI systems. That is, Agile BI systems need to support business agility. To support business agility, BI systems should address three main attributes: Usable and Extensible – In a recent TDWI webinar on business […]
