Every effort has been made to preserve the original process flow diagram structures, calculations, and results, but technical enhancements to the software might result in some perceptible differences between the original and the converted process flow diagrams. Converted process flow diagrams might contain additional nodes, substituted nodes, or enhanced nodes. These incremental changes often improve the computational accuracy of the node, so some variation in results might exist between the original and converted project process flow diagrams.
When comparing original and converted project process flow diagrams and their results, you should expect to see differences in the implementation of the following SAS Enterprise Miner 4.
When performing stratified sampling in a process flow diagram, the default settings of SAS Enterprise Miner 4. Then, you use the Stratification tab to choose your stratification variable from the available nominal and ordinal variables in your data set:.
If no stratification variable status is set to use , then no stratification sampling will be performed. Instead, the Sampling node reverts to simple random sampling, because data cannot be sampled by strata without a declared stratification variable. You must change the status of a class variable from its default setting of don't use to use to perform stratified sampling. Then, you must open the Variables property window to choose your stratification variable by assigning the Sample Role :.
You must assign the Sample Role of Stratification to your desired stratification variable, and you must also assign the Sample Role of None to the remaining variables. If there are no class targets, then the node will perform random sampling by default.
Otherwise, the default settings of the Sample node might differ. When performing stratified data partitioning in a process flow diagram, the default settings of the SAS Enterprise Miner 4. Then, use the Stratification tab to choose your stratification variable from the available class variables in your data set:. If no stratification variable status is set to use , then no stratification is performed. Instead, the Data Partition node reverts to performing simple random data partitioning, because data cannot be partitioned by strata without a declared stratification variable.
You must change the status of a class variable from its default setting of don't use to use to perform stratified data partitioning. If you specify Stratified as the Partitioning Method , you must open the Variables property window to choose your stratification variable by specifying the Partition Role for the stratification variable:.
Assign the Partition Role of Stratification to your desired stratification variable, and then assign the Partition Role of None to the remaining variables. If no class target is found, all class binary, nominal, and ordinal variables will be used to perform stratified data partitioning. Differently partitioned data can alter the analytical results of your converted SAS Enterprise Miner 5. The Tree Desktop Application version 9.

Before we begin, know that an Enterprise Miner project is composed of many different files and folders and many of which are not portable to a different operating system.
This means that the process of moving or migrating an Enterprise project is not as simple as a copy. This includes moving SAS Enterprise Miner projects to or from bit and bit systems, and to or from different Enterprise Miner supported operating systems.
Even locale and encoding are converted in this process. Supported versions include Enterprise Miner 6. Fortunately, the project migration process preserves both. This means if you examine the Results for each node in a migrated project, they will be exactly the same as the old system.
