Understand

A detection of the level of non-Gaussianity in the CMB data is essential to discriminate among inflationary models and also to test alternative primordial scenarios.

However, the extraction of primordial non-Gaussianity is a difficult endeavor since several effects of non-primordial nature can produce non-Gaussianity.
On the other hand, different statistical tools can in principle provide information about distinct forms of non-Gaussianity.
Thus, any single statistical estimator cannot be sensitive to all possible forms of non-Gaussianity.
