Testing Inverse Gaussian Versus Log Normal [PDF]

open access: yesThe Egyptian Statistical Journal, 1991
The inverse Gaussian distribution has been proposed as a model for distribution of life times. It is considered as an alternative to other observed distributions in particular to the lognormal.

An Approximate Closed Formula for European Mortgage Options

open access: yesTrends 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 ...

An EM Algorithm for Double-Pareto-Lognormal Generalized Linear Model Applied to Heavy-Tailed Insurance Claims

open access: yesRisks, 2017
Generalized linear models might not be appropriate when the probability of extreme events is higher than that implied by the normal distribution. Extending the method for estimating the parameters of a double Pareto lognormal distribution (DPLN) in Reed ...

Variability in the Log Domain and Limitations to Its Approximation by the Normal Distribution

open access: yesCPT: 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

open access: yesIEEE 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 ...

SPATIAL AUTOREGRESSIVE (SAR) MODEL WITH ENSEMBLE LEARNING-MULTIPLICATIVE NOISE WITH LOGNORMAL DISTRIBUTION (CASE ON POVERTY DATA IN EAST JAVA)

open access: yesMedia Statistika, 2021
The regression model that can be used to model spatial data is Spatial Autoregressive (SAR) model. The level of accuracy of the estimated parameters of the SAR model can be improved, especially to provide better results and can reduce the error rate by ...
