class mvpa2.clfs.transerror.RegressionStatistics(**kwargs)

Class to contain information and display on regression results.

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 statistics
compute()	Actually compute the confusion matrix based on all the sets
plot([plot, plot_stats, splot])	Provide presentation of regression performance in image
reset()	Cleans summary – all data/sets are wiped out

Initialize RegressionStatistics

Parameters:

targets

Optional set of targets

predictions

Optional set of predictions
