Display the statistic values for the current background models.

Returns the statistics values for background datasets with background models. See calc_stat_info for a description of the return value.

Added in version 4.16.0.


If a fit to a particular background data set has not been made, or values - such as parameter settings, the noticed data range, or choice of statistic - have been changed since the last fit, then the results for that data set may not be meaningful and will therefore bias the results for the simultaneous results.
