Bases:
NoNewAttributesAfterInit
A summary of the current statistic value for one or more data sets.
- ids
The data set ids (it may be a tuple or array) included in the results.
- Type
sequence of int or str
- bkg_ids
The background data set ids (it may be a tuple or array) included in the results, if any.
- Type
sequence of int or str, or None
- statval
The statistic value.
- Type
number
- dof
The number of degrees of freedom in the fit (the number of bins minus the number of free parameters).
- Type
- qval
The Q-value (probability) that one would observe the reduced statistic value, or a larger value, if the assumed model is true and the current model parameters are the true parameter values. This will be
None
if the value can not be calculated with the current statistic (e.g. the Cash statistic).- Type
number or None
- rstat
The reduced statistic value (the
statval
field divided bydof
). This is not calculated for all statistics.- Type
number or None
