Random processes in nature often underlie a so - called normal distribution that enables reliable estimation for the appearance of extreme statistical events.

In the normal distribution of a bell curve, you never get such extremes, but the pattern underlying the power curve enables a few rare events of extraordinary magnitude.

Assume that the underlying asset has a log - normal return distribution with mean μ = r − q − σ2 / 2 and variance σ2.

Extreme outliers can spoil the fit, not because of any inherent weakness of the method but because their presence indicates that the underlying assumption does not hold, i.e. the noise does not follow a normal distribution — not even approximately.

jkutney — The CLT is useful precisely because the underlying distribution doesn't have to be normal.

If some primary studies report an outcome as a dichotomous measure and others use a continuous measure of the same construct, we will convert results for the former from an OR to a SMD, provided that we can assume the underlying continuous measure has approximately a normal or logistic distribution (otherwise we will perform two separate analyses).
