mvpa2.clfs.transerror.SummaryStatistics¶
- class mvpa2.clfs.transerror.SummaryStatistics(targets=None, predictions=None, estimates=None, sets=None)¶
Basic class to collect targets/predictions and report summary statistics
It takes care about collecting the sets, which are just tuples (targets, predictions, estimates). While ‘computing’ the matrix, all sets are considered together. Children of the class are responsible for computation and display.
Initialize SummaryStatistics
targets or predictions cannot be provided alone (ie targets without predictions)
Parameters : targets :
Optional set of targets
predictions :
Optional set of predictions
estimates :
Optional set of estimates (which served for prediction)
sets :
Optional list of sets
- add(targets, predictions, estimates=None)¶
Add new results to the set of known results
- as_string(short=False, header=True, summary=True, description=False)¶
‘Pretty print’ the matrix
Parameters : short : bool
if True, ignores the rest of the parameters and provides consise 1 line summary
header : bool
print header of the table
summary : bool
print summary (accuracy)
description : bool
print verbose description of presented statistics
- compute()¶
Actually compute the confusion matrix based on all the sets
- error¶
- reset()¶
Cleans summary – all data/sets are wiped out
- sets¶
- stats¶
- summaries¶
Return a list of separate summaries per each stored set
