Analysis of Exchange Rates as Time-Inhomogeneous Markov Chain with Finite States
Journal of Applied Mathematics, 2022 Irrespective of whether the test for homogeneity is significant or not, most researchers assume time-homogeneity in analysing Markov chains due to scanty literature on the analysis of time-inhomogeneous Markov chains.

Volatility Analysis of Exchange Rate with Correlated Errors: A Sliding Data Matrix Approach
Journal of Applied Mathematics, 2022 The main objective of this study is to propose a method of analysing the volatility of a seemingly random walk time series with correlated errors without transforming the series as performed traditionally.

Estimation of the Tail Index of Pareto-Type Distributions Using Regularisation
Journal of Mathematics, 2022 In this paper, we introduce reduced-bias estimators for the estimation of the tail index of Pareto-type distributions. This is achieved through the use of a regularised weighted least squares with an exponential regression model for log-spacings of top ...

Implementation of Correlation and Regression Models for Health Insurance Fraud in Covid-19 Environment using Actuarial and Data Science Techniques [PDF]
Int. J. Recent Technol. Eng. vol. 9 no. 3 pp. 699-706 Sep. 2020, 2021 Fraud acts as a major deterrent to a companys growth if uncontrolled. It challenges the fundamental value of Trust in the Insurance business. COVID-19 brought additional challenges of increased potential fraud to health insurance business. This work describes implementation of existing and enhanced fraud detection methods in the pre-COVID-19 and COVID ...

A New Generated Family of Distributions: Statistical Properties and Applications with Real-Life Data
Computational and Mathematical Methods, 2023 Several standard distributions can be used to model lifetime data. Nevertheless, a number of these datasets from diverse fields such as engineering, finance, the environment, biological sciences, and others may not fit the standard distributions.

Forecasting age distribution of death counts: An application to annuity pricing [PDF]
Annals of Actuarial Science, 2020, 14(1), 150-169, 2019 We consider a compositional data analysis approach to forecasting the age distribution of death counts. Using the age-specific period life-table death counts in Australia obtained from the Human Mortality Database, the compositional data analysis approach produces more accurate one- to 20-step-ahead point and interval forecasts than Lee-Carter method ...
