Specification Search
Limiting the number of models reported can speed up a specification search
significantly. However, only eight models in total will be encountered during the
specification search for this example, and specifying a nonzero value for
Retain only
the best ___ models
would have the undesirable side effect of inhibiting the program
from normalizing Akaike weights and Bayes factors so that they sum to 1 across all
models, as seen later.
E Close the Options dialog box.
Performing the Specification Search
E Click on the Specification Search toolbar.
The program fits the model eight times, using every subset of the optional arrows.
