An Approximate Closed Formula for European Mortgage Options
Trends in Computational and Applied Mathematics, 2023 The aim of this paper is to investigate the use of close formula approximation for pricing European mortgage options. Under the assumption of logistic duration and normal mortgage rates the underlying price at the option expiry is approximated by ...

Variability in the Log Domain and Limitations to Its Approximation by the Normal Distribution
CPT: Pharmacometrics & Systems Pharmacology, 2020 Pharmacometric models using lognormal distributions have become commonplace in pharmacokinetic–pharmacodynamic investigations. The extent to which it can be interpreted by traditional description of variability through the normal distribution remains ...

A Bayesian Angular Superresolution Method With Lognormal Constraint for Sea-Surface Target
IEEE Access, 2020 Maximum a posteriori (MAP) approach, based on Bayesian criterion, is proposed to overcome the low azimuth resolution in real-aperture imaging. The essence of this approach is to use the statistical characteristics of the imaging background and target to ...

On the Tails of the Distribution of the Sum of Lognormals [PDF]
2007 IEEE International Conference on Communications, 2007 Finding the distribution of the sum of lognormal random variables is an important mathematical problem in wireless communications, as well as in many other fields. While several methods exist to approximate this distribution, their performance tends to deteriorate in both tails. Finding a good overall fit remains an open problem. Other disadvantages of
