Dear All: Does anybody know anything about the distribution and distributional properties of the difference of two lognormally distributed random variables? By simulation, I found that it is maybe some of Levi's stable distributions. Maybe. Is there any way to validate such an assumption? Any ideas, references are highly appreciated. Thank you in advance Xao Ping A&A pharmakinetics Taiwan
