Bonus-Malus Premiums Based on Claim Frequency and the Size of Claims

Risks, 2022
The bonus-malus system (BMS) is one of the most widely used tools in merit-rating automobile insurance, with the primary goal of ensuring that fair premiums are paid by all policyholders. The traditional BMS is dependent only on the claim frequency. Thus,

Double Generalized Beta-Binomial and Negative Binomial Regression Models

Revista Colombiana de Estadística, 2017
Overdispersion is a common phenomenon in count datasets, that can greatly affect inferences about the model. In this paper develop three joint mean and dispersion regression models in order to fit overdispersed data.

Parameter estimation of the beta-binomial distribution: an application using the SAS software Estimação dos parâmetros da distribuição beta-binomial: uma aplicação usando o

, 2015
In this paper we describe the parameter estimation of the beta-binomial distribution using the procedure NLMIXED of the SAS software. The beta-binomial distribution is a discrete mixture distribution which can capture overdispersion in the data.

Bivariate stochastic modeling of functional response with natural mortality [PDF]

, 2010
A correction due to Abbott (1925) is the standard method of dealing with control mortality in insect bioassay to estimate the mortality of an insect conditional on control mortality not having occurred.

The Risk Priority Number Evaluation of FMEA Analysis Based on Random Uncertainty and Fuzzy Uncertainty

Complexity, 2021
The risk priority number (RPN) calculation method is one of the critical subjects of failure mode and effects analysis (FMEA) research. Recently, RPN research under a fuzzy uncertainty environment has become a hot topic.

On testing exponentiality under Type-I censoring

Frontiers in Applied Mathematics and Statistics, 2023
Two new goodness-of-fit testing procedures are introduced to test exponentiality when data are subject to Type-I censoring. We proposed four test statistics for this purpose.

Migraine day frequency in migraine prevention: longitudinal modelling approaches

BMC Medical Research Methodology, 2019
Background Health economic models are critical tools to inform reimbursement agencies on health care interventions. Many clinical trials report outcomes using the frequency of an event over a set period of time, for example, the primary efficacy outcome ...

A beta-Poisson model for infectious disease transmission.

PLoS Computational Biology
Outbreaks of emerging and zoonotic infections represent a substantial threat to human health and well-being. These outbreaks tend to be characterised by highly stochastic transmission dynamics with intense variation in transmission potential between ...
