stanmodel-class: Class representing model compiled from C++
Description
A stanmodel
object represents the model compiled from C++ code.
The sampling
method defined in this class may be used to
draw samples from the model and optimizing
method is for
obtaining a point estimate by maximizing the log-posterior.Objects from the Class
Instances of stanmodel
are usually created by calling
function stan_model
or function stan
.Slots
model_name
:- The model name, an object of type
character
.
model_code
:- The Stan model specification, an object of type
character
.
model_cpp
:- Object of type
list
that includes the C++ code for the model.
mk_cppmodule
:- A function to return a RCpp module. This function will be
called in function
sampling
and optimzing
with one
argument (the instance of stanmodel
itself).
dso
:- Object of S4 class
cxxdso
. The container for the dynamic
shared objects compiled from the C++ code of the model, returned from function
cxxfunction
in package inline.
Methods
show
signature(object = "stanmodel")
: print the Stan model specification.
vb
signature(object = "stanmodel")
: use the variational Bayes algorithms.
sampling
signature(object = "stanmodel")
: draw samples for
the model (see sampling
).
optimizing
signature(object = "stanmodel")
: obtain a point
estimate by maximizing the posterior (see optimizing
).
get_cppcode
signature(object = "stanmodel")
: return the C++ code for the model
as a character string. This is part of the C++ code that is compiled to the dynamic
shared object for the model.
get_cxxflags
signature(object = "stanmodel")
: return the CXXFLAGS
used for compiling the model. The returned string is like CXXFLAGS = -O3
.
