Syntax#
v = fix_likelihood.forward (0, theta )
fix_likelihood#
is a d_fun representation of the negative log of the fixed effects likelihood
\[f( \theta )
=
v_0 ( \theta ) + | v_1 ( \theta) | + \cdots + | v_{m-1} ( \theta ) |
=
- \log [ \B{p} ( z | \theta ) \B{p} ( \theta ) ]\]
The functions \(v_i ( \theta )\) for \(i = 0 , \ldots , m-1\) are assumed to be a smooth w.r.t the vector \(\theta\).
theta#
is a numpy vector with float elements and size
n_fixed
containing a value for the fixed effects.
v#
is a numpy vector with float elements and size m.
None#
The value fix_likelihood = None
corresponds to the fixed effects likelihood
being constant w.r.t. \(\theta\).
