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.

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 ...
