In a PROC TEXTMINE followed by PROC DMDB and PROC NEURAL pipeline, what role does PROC DMDB play?
Select an answer to reveal the explanation.
Short Explanation
Here's the deal — PROC DMDB creates a descriptive metadata file about dataset variables, such as types, class levels, and statistics, that downstream SAS data mining procedures like PROC NEURAL need. You're not using it to score models or transform text features.
Full Explanation
PROC DMDB is correct because it creates a descriptive metadata file about dataset variables (types, class levels, statistics) required as input by SAS data mining procedures including PROC NEURAL, PROC CLUSTER, and others. The model-scoring option is wrong; scoring uses PROC ASTORE or PROC SCORE. The SVD option is wrong; SVD is performed within PROC TEXTMINE. The merging option describes a data preparation step, not PROC DMDB's function.
