4.1.2.2.1.1.2. statsmodels.base._constraints.TransformRestriction.expand

TransformRestriction.expand(params_reduced)

transform from the reduced to the full parameter space

Parameters:

params_reduced : array_like

Returns:

params : array_like

parameters in the original space

Notes

If the restriction is not homogeneous, i.e. q is not equal to zero, then this is an affine transform.
