Published in 2019 at "Finance Research Letters"

DOI: 10.1016/j.frl.2018.04.006

Abstract: Abstract We evaluate a utility indifference price with an exponential utility function, which we call a risk-sensitive value measure, under a normal mixture distribution with time-varying volatility. We compare the risk-sensitive value measure and mean-variance… read more here.

Published in 2020 at "Journal of Applied Statistics"

DOI: 10.1080/02664763.2020.1769578

Abstract: Conformance proportions are important numerical indices for quality assessments. When the population is characterized by a normal mixture model, estimating conformance proportions can be a practical issue. To account for the inherent structure of normal… read more here.

Published in 2018 at "Communications in Statistics - Theory and Methods"

DOI: 10.1080/03610926.2018.1481972

Abstract: Abstract– It is well known that there exist multiple roots of the likelihood equations for finite normal mixture models. Selecting a consistent root for finite normal mixture models has long been a challenging problem. Simply… read more here.

Published in 2022 at "BioMed Research International"

DOI: 10.1155/2022/8310213

Abstract: Huxley's model of simple allometry provides a parsimonious scheme for examining scaling relationships in scientific research, resource management, and species conservation endeavors. Factors including biological error, analysis method, sample size, and overall data quality can… read more here.

Published in 2020 at "Statistica Sinica"

DOI: 10.5705/ss.202016.0483

Abstract: Although normal mixture models have received great attention and are commonly used in different fields, they stand out for failing to have a finite maximum on the likelihood. In the univariate case, there are n… read more here.
