obtain transformed thresholds from original thresholds or cutoffs

Parameters:¶

paramsndarray

Threshold values, cutoff constants for choice intervals, which need to be monotonically increasing.

Returns:¶

thresh_paramsndarrray

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.
