TL;DR: In this paper, the class of modified power series distributions is widened by removing the restriction that the functions f(z) and g(z), as two probability generating functions defined on nonnegative integers, be probability generation functions.
Abstract: Starting with the second Lagrange expansion, with f(z) and g(z) as two probability generating functions defined on non-negative integers, Janardan and Rao( 1983) introduced a new class of discrete distributions called the Lagrange Distributions (LD2) of the second kind. In this note, this class of LD2 distributions is widened by removing the restriction that the functions f(z) and g(z) be probability generation functions. It is also shown that the class of modified power series distributions is a subclass of LD2.

TL;DR: A validation scheme for the model is suggested using the theoretical joint moments corresponding to the generalized K-distribution, which is in the form of a one-dimensional integral-difficult to be tested experimentally.
Abstract: A generalized polarimetric K-distribution is derived for characterizing multi-look fully polarimetric SAR data, on the basis that the underlying texture structures in polarization channels assume a trivariate joint gamma distribution with partial correlation and that the co-polarized and cross-polarized speckle components are de-correlated. Since the resulting K-distribution is in the form of a one-dimensional integral-difficult to be tested experimentally-a validation scheme for the model is then suggested using the theoretical joint moments corresponding to the generalized K-distribution.
