class
sherpa.fit.ErrorEstResults(fit, results, parlist=None)[source] [edit on github]¶ Bases:
sherpa.utils.NoNewAttributesAfterInitThe results of an error estimation run.
This object contains the parameter ranges, information on the statistic and optimisation-method used, and other relevant information.
-
datasets¶ A sequence of the data set ids included in the results.
Type: sequence of int or str, or None
-
methodname¶ The name of the optimisation method used (in lower case).
Type: str
-
itermethodname¶ What iterated-fit scheme was used, if any.
Type: str or None
-
fitname¶ The name of the method used to fit the data, in lower case.
Type: str
-
statname¶ The name of the statistic used to fit the data, in lower case.
Type: str
-
sigma¶ The error values represent this number of sigma (assuming a Gaussian distribution).
Type: number
-
percent¶ The percentage value for the errors (calculated from the
sigmavalue assuming Gaussian errors).Type: number
-
parnames¶ the parameter names that were varied in the fit (the thawed parameters in the model expression).
Type: tuple of str
-
parvals¶ The parameter values, in the same order as parnames.
Type: tuple of number
-
parmins¶ The parameter minimum values, in the same order as parnames.
Type: tuple of number
-
parmaxes¶ The parameter maximum values, in the same order as parnames.
Type: tuple of number
-
nfits¶ The number of fits performed during the error analysis.
Type: int
