WebApr 1, 2010 · Podobnik et al. [12] developed a scale-invariant truncated Lévy (STL) process that exhibits Lévy stability for the distribution in order to describe physical systems characterized by correlated stochastic variables. It has the advantage that all moments are finite and thus it accounts for the empirical scaling of the moments. WebThe exponent (α{\displaystyle \alpha }) is an empirically derived coefficient that varies dependent upon the stability of the atmosphere. For neutral stabilityconditions, α{\displaystyle \alpha }is approximately 1/7, or 0.143.
