Syntax#
v = fix_constraint.forward (0, theta )
fix_constraint#
is a d_fun representation of the fixed effects constraint function
\[g( \theta )
=
[ v_0 ( \theta ) , \cdots , v_{m-1} ( \theta ) ]^\R{T}\]
The functions \(v_i ( \theta )\) for \(i = 0 , \ldots , m-1\) are assumed to be a smooth w.r.t the vector \(\theta\). The bounds for \(g( \theta )\) are specified by fix_constraint_lower (fix_constraint_upper) .
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_constraint = None
corresponds to not fixed effects constraint function; i.e.,
\(m = 0\).
