comment Identifying a critical phenomena?
i think so. the problem is that to show that the mean or variance in the data are not finite is not trivial.

comment The meaning of scale invariance in power law distribution
you can build distribution without mean and variance that are not scale invariant. See stable distributions on wikipedia.

I think that there is an error on your changing the limits of integration.

comment The meaning of scale invariance in power law distribution
Yes of course. There are boundaries in integration. I have omitted because the does not matters on the derivation of the property. I don't want to prove nothing. I would like to know the meaning of first scale property, if any.

you right. There is a mistake.

comment The meaning of scale invariance in power law distribution
What i means is that defining $f(ax)=a^\Delta f(x)$ as scale invariant property is misleading, because the distribution function is not invariant for a generic value of $\Delta$.
