OrderedModel.transform_threshold_params(params)[source]

transformation of the parameters in the optimization

Parameters:
params : nd_array

Contains (exog_coef, transformed_thresholds) where exog_coef are the coefficient for the explanatory variables in the linear term, transformed threshold or cutoff points. The first, lowest threshold is unchanged, all other thresholds are in terms of exponentiated increments.

Returns:

thresh – Thresh are the thresholds or cutoff constants for the intervals.

Return type:
