DynamicFactorMQ.untransform_params(constrained)[source]¶

Transform parameters from model space to optimizer space.

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.
