HSICEstimator

class HSICEstimator(*args)

Base class of HSIC estimators.

See also

HSICEstimatorConditionalSensitivity, HSICEstimatorGlobalSensitivity, HSICEstimatorTargetSensitivity

Notes

HSIC-based analyses must be performed by using the derived classes: HSICEstimatorConditionalSensitivity, HSICEstimatorGlobalSensitivity and HSICEstimatorTargetSensitivity.

The ResourceMap key HSICEstimator-InputCovarianceMatrixCacheSizeMb allows one to limit the total size (in mega bytes) of the input matrix cached.
