Is Power Law heavy tailed?
A particular subclass of heavy tail distributions is power-laws, which means that the PDF is a power. In its place is a new standard limit distribution for linear combinations such as means, namely the stable distribution.
What is a truncated power law?
As explained in this wiki article (albeit briefly), a “truncated” or “cutoff” power law distribution is simply a power law multiplied by an exponential (by definition). The term “cutoff” or “truncated” is a misnomer (when compared to distributions like truncated normal) since the range is not affected.

How to analyze a heavy tailed power law?
Basic steps of analysis for heavy-tailed distributions: visualizing, fitting, and comparing. Example data for power law fitting are a good fit (left column), medium fit (middle column) and poor fit (right column). Data and methods described in text.
Can a power law be a probability distribution?
Power-law functions. Mathematically, a strict power law cannot be a probability distribution, but a distribution that is a truncated power function is possible: for where the exponent (Greek letter alpha, not to be confused with scaling factor used above) is greater than 1 (otherwise the tail has infinite area),…
