# statsmodels.regression.recursive_ls.RecursiveLS.untransform_params¶

RecursiveLS.untransform_params(constrained)

Transform constrained parameters used in likelihood evaluation to unconstrained parameters used by the optimizer

Parameters: constrained (array_like) – Array of constrained parameters used in likelihood evalution, to be transformed. unconstrained – Array of unconstrained parameters used by the optimizer. array_like

Notes

This is a noop in the base class, subclasses should override where appropriate.
