Query: On the Approximation of the Sum of Lognormals by a Log Skew Normal
  Distribution   Several methods have been proposed to approximate the sum of lognormal RVs.
However the accuracy of each method relies highly on the region of the
resulting distribution being examined, and the individual lognormal parameters,
i.e., mean and variance. There is no such method which can provide the needed
accuracy for all cases. This paper propose a universal yet very simple
approximation method for the sum of Lognormals based on log skew normal
approximation. The main contribution on this work is to propose an analytical
method for log skew normal parameters estimation. The proposed method provides
highly accurate approximation to the sum of lognormal distributions over the
whole range of dB spreads for any correlation coefficient. Simulation results
show that our method outperforms all previously proposed methods and provides
an accuracy within 0.01 dB for all cases.
