PurityRBFitter.fit_data()[source]

Fit the Purity RB results to an exponential curve.

Use the data to construct guess values for the fits.

Puts the results into a list of fit dictionaries where each dictionary corresponds to a pattern and has fields:

• params - three parameters of rb_fit_fun. The middle one is the exponent.

• err - the error limits of the parameters.

• epc - Error per Clifford.

• pepc - Purity Error per Clifford.
