# Package measures

source code

PyMVPA measures.

# Module Description

Provide some measures given a dataset. Most of the time, derivatives of FeaturewiseDatasetMeasure are used, such as

- OneWayAnova
- CorrCoef
- IterativeRelief
- NoisePerturbationSensitivity

Also many classifiers natively provide sensitivity estimators via the call to `getSensitivityAnalyzer` method

- mvpa.measures.ds: Dissimilarity measure.
- mvpa.measures.glm: The general linear model (GLM).
- mvpa.measures.irelief: FeaturewiseDatasetMeasure performing multivariate Iterative RELIEF (I-RELIEF) algorithm. See : Y. Sun, Iterative RELIEF for Feature Weighting: Algorithms, Theories, and Applications, IEEE Trans. on Pattern Analysis and Machine Intelligence (TPAMI), vol. 29, no. 6, pp. 1035-1051, June 2007.
- mvpa.measures.noiseperturbation: This is a FeaturewiseDatasetMeasure that uses a scalar DatasetMeasure and selective noise perturbation to compute a sensitivity map.
