Examples
-
While the limits on non-Gaussianity as it is called, from analysis of the WMAP data, only weakly constrain various models of inflation, they do leave almost nowhere for cosmological models without inflation to hide.
-
Another is the giant cold spot (or “non-Gaussianity,” if you want to sound like an expert) — the Southern hemisphere seems to have a suspiciously coherent blob of slightly lower than average CMB temperature.

The model makes several predictions, including non-Gaussianity and modifications to the inflationary consistency relation, that will be tested with forthcoming CMB experiments.

-
Contrary to earlier claims, we find that the amount of power concentrated in planar modes for $\ell = 2,3$ is not inconsistent with isotropy and Gaussianity.
-
Thhis is a signature of what is known as, “non-Gaussianity”, which contradicts the simplest models of inflation, requiring more bandaids and cream.
-
Conversely, when RTs were the dependent variable, a Gaussian distribution was assumed, with a log link function to obtain a better fit to Gaussianity (typically and also in our study, RTs follows an almost log-normal distribution).
