- OrderedModel.transform_reverse_threshold_params(params)[source]¶
obtain transformed thresholds from original thresholds or cutoffs
- Parameters:
- params
ndarray
Threshold values, cutoff constants for choice intervals, which need to be monotonically increasing.
- params
- Returns:
- thresh_params
ndarrray
Transformed threshold parameter. The first, lowest threshold is unchanged, all other thresholds are in terms of exponentiated increments. Transformed parameters can be any real number without restrictions.
