Using IBM SPSS Modeler with a Repository
Scoring node.
Select a graph, output or export node to identify the stream branch to be used for
scoring the da
ta. While the stream can actually con tain any number of valid branches, models, and
terminal nodes, one and o nly one scoring branch must be designated f or p urposes of deployment.
This is the most basic requirement to deploy any stream.
Scoring Parameters.
Allows you to specify parameters that can be modified when the scoring
branch is run. For more information, see the topic Scoring and Modeli ng Parameters on p. 188.
Modeling node.
For model re f resh, specifies the modeling node used to regenerate or update the
model in the repository. Must be a modeling node of the same type as that specifie d for Model
nugget.
Model Build Parameters.
Allows you to specify parameters that can be modified when the modeling
node is run. For more information, see the topic Scoring and Modeling Parameters on p. 188.
Model nugget.
For model re f r esh, specifies the model nugget that will be updated or regenerated
each time the stream is u pdated in the r epositor y (typically as part of a scheduled job). The model
must be located on the scoring branch. While multiple models may exist on the scoring branch,
only one can be designated. Note that when the stream is initially created this may effectively be a
placeholder model that is updated or regenerated as new data is available.
Deploy as stream.
Click this option if you want to use the stream with IBM SPSS Modeler
Advantage or IBM SPSS Collaboration and Depl oyment Services (and see note following).
Deploy as scenario.
Cli
ck this option if you want to use the stream with IBM SPSS Collaboration
and Deployment Services or Predictive Applications version 5 (and see note fol lowing).
Check
. Click this button to check whether th is is a valid stream for deployment. All streams mu st
have a design ated scoring node before they can be deploy ed. If you are deploy ing as a scenario,
the s tream must also contain a valid Enterprise View source node. Error messages are displayed
if these conditions are not satisfied.
Store
. D eploys the stream if it is valid. If not, an error message is displayed. Click the Fix button,
correct the error and try again.
Preview Stream Description.
Enables yo u to view the contents of the strea m description that SPSS
Modeler creates for the stream. For more inf ormation, see the topic Stream Descrip tions in
Chapter 5 on p. 74.
Note: (Deploy as stream or scenario) Multiple Enterpr is e View nodes can be used within the
modeling branch. If so, using a single data connection for all Enterprise View nodes within the
branch is preferable in most cases, and is required for Champion Challenger analysis.
If Champion Challenger support is not required, different Enterprise View connections can
be used within the same branch, as long as the connections vary by data provider definition
(DPD) only.
These limitations apply w ithin a given branch only. Between the scoring and model building
branches, d iffere nt Enterprise View connections can be used withou t such r estrictions.
