When setting up models to be fitted by the estimation functions,
users typically only specify some of the details of the priors for
the main effects or interactions. The remaining details are filled in
by the estimation functions, based on the input data. Function
showModel
can be used find out what choices the estimation
functions made.
To see the partial specification constructed by function
Model
, print the model object (typically by typing
the name of the object at the console.) See below for an example.
show fetch
.
The trunc-half-t(df, s^2, max)
in the printed results refers to a
truncated half-t
distribution with df
degrees of freedom, scale s^2
, and maximum value max
.
showModel
is called for its side effect, which is to print a
description of the model.
Parameter estimate can be extracted using function
fetch
.
