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.

Attributes

error
sets
stats
summaries	Return a list of separate summaries per each stored set

Methods

add(targets, predictions[, estimates])	Add new results to the set of known results
as_string([short, header, summary, description])	‘Pretty print’ the matrix
compute()	Actually compute the confusion matrix based on all the sets
reset()	Cleans summary – all data/sets are wiped out

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

Methods

add(targets, predictions[, estimates])	Add new results to the set of known results
as_string([short, header, summary, description])	‘Pretty print’ the matrix
compute()	Actually compute the confusion matrix based on all the sets
reset()	Cleans summary – all data/sets are wiped out

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
