Create data sources from SAS tables in Enterprise Miner 
 Use the Basic Metadata Advisor  Use the Advanced Metadata Advisor  Customize the Advanced Metadata Advisor  Set Role and Level meta data for data source variables  Set the Role of the table (raw, scoring, transactional, etc) 
Explore and assess data sources 
 Create and interpret plots, including Histograms, Pie charts, Scatter plot, Time series, Box plot  Identify distributions  Find outlying observations  Find number (or percent) of missing observations  Find levels of nominal variables  Explore associations between variables using plots by highlighting and selecting data  Compare balanced and actual response rates when oversampling has been performed  Explore data with the STAT EXPLORER node.  Explore input variable sample statistics  Browse data set observations (cases) 
Modify source data 
 Replace zero values with missing indicators using the REPLACEMENT node  Use the TRANFORMATION node to be able to correct problems with input data sources, such as variable distribution or outliers.  Use the IMPUTE node to impute missing values and create missing value indicators  Reduce the levels of a categorical variable  Use the FILTER node to remove cases 
Prepare data to be submitted to a predictive model 
 Select a portion of a data set using the SAMPLE node  Partition data with the PARTITION Node  Use the VARIABLE SELECTION node to identify important variables to be included in a predictive model.  Use the PARTIAL LEAST SQUARES node to identify important variables to be included in a predictive model.  Use a DECISION TREE or REGRESSION nodes to identify important variables to be included in a predictive model.
