get_precarity_index()

Computes precarity from start-state cost, complexity, and degradation correction.

Function

from sequenzo import get_precarity_index
result = get_precarity_index(seqdata, otto=0.2, a=1.0, b=1.2, method="TRATEDSS")

Parameters

• seqdata: SequenceData object.
• otto, a, b: combination and power parameters.
• method: method used when correction is computed internally.
• optional: correction, state_order, state_equiv, stprec, with_missing, pow.

Returns

DataFrame with Prec values per sequence.
