ode> is not a parameter,
transformed parameter, or local model variable, the sampling statement
is clever enough to drop the <code>log(lambda)</code> term. This results in
the same posterior because Stan only needs the log probability up to
an additive constant. If <code>lambda</code> and <code>y</code> are both
constants, the sampling statement will drop both terms (but still
check for out-of-domain errors on the inputs).</p>
