A Note on a Generalized Gerber–Shiu Discounted Penalty Function for a Compound Poisson Risk Model

open access: yesMathematics, 2019
In this paper, we propose a new generalized Gerber−Shiu discounted penalty function for a compound Poisson risk model, which can be used to study the moments of the ruin time.

A General Solution for the Errors in Variables (EIV) Model with Equality and Inequality Constraints

open access: yesApplied Sciences, 2022
Targeting the adjustment of the errors-in-variables (EIV) model with equality and inequality constraints, a general solution that is similar to the classical least square adjustment is proposed based on the penalty function and the weight in measurement.
