Theorem 21 then establishes a quantum central limit theorem
for these observables.
The Central Limit Theorem
accounts for the popularity of [bar.x] as a measure of central tendency.
We note that although the derivation here is based on the approach to the Gaussian distribution on the basis of the central limit theorem
, the same type Edgeworth expansion can also be found in the context of nonlinear evolution of density fluctuations starting from random Gaussian linear fluctuations.

Describe in your own words the (celebrated) Central Limit Theorem
. What assumptions must be met in order to use its conclusions?

A second argument sometimes mentioned in support of the log-normal distribution is based on the central limit theorem
, which implies that under certain regularity conditions the distribution of a product of random variables will approach log normality as the number of terms increases.
The formulation of an accompanying central limit theorem
takes into account that there is no convenient notion of subtraction for convex bodies, and so the identification with support functions is used:
Note that the sum in the denominator above converges to 1/2 by the Central Limit Theorem
