RecursiveLS.untransform_params(constrained)

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

Parameters
constrainedarray_like

Array of constrained parameters used in likelihood evaluation, to be transformed.

Returns
unconstrainedarray_like

Array of unconstrained parameters used by the optimizer.

Notes

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