OPEN SOURCE

INTEGRATION

THIS IS ACHIEVED WITH SAS ANALYTICS IN

ACTION

• Data is about gathering data from the different data sources and locations, unifying

it and making it ready for modeling

• Discovery is about having the flexibility to prototype analytical models to uncover

business value

• Deployment is about engineering enterprise level solutions from those prototypes

with governance measures to ensure quality

USING R IN SAS

ENTERPRISE MINER

• Enables the execution of R code within an Enterprise Miner workflow.

• Transfers data, metadata, and results automatically between Enterprise Miner

and R

USING R IN SAS

ENTERPRISE MINER

Predictive modeling markup language (PMML) is an open standard

enabling certain R models to be translated into SAS DATA step code

PMML OUTPUT

Currently supported R models include:

• Linear Models (lm)

• Multinomial Log-Linear Models

(multinom (nnet))

• Generalized Linear Models (glm (stats))

• Decision Trees (rpart)

• Neural Networks (nnet)

• k-means Clustering (kmeans (stats))

Merge output mode enables integration with thousands of R packages that

are not supported in PMML output mode.

MERGE OUTPUT MODE

Variables created in R are merged with SAS

Enterprise Miner data sources by the user.

SAS DATA step code is not created.

ENTERPRISE MINERSOME PRECAUTIONS

Some items to consider when running R models in Open Source

note:

• Missing Values may be an issue

• Ensure Categorical Variables are not high in cardinality

• Memory issues
