Measuring rank mobility with variable population size

Escaping the repugnant conclusion: Rank-discounted utilitarianism with variable population

We contribute to population ethics by proposing and axiomatizing rankdiscounted critical-level generalized utilitarianism (RDCLU). Population ethics is needed for evaluation of policies, e.g., concerning climate change, where population size depends on the chosen policy. We show that critical-level generalized utilitarianism and (a version of) critical-level leximin are the limits of RDCLU for ...

Fluctuations in a SIS epidemic model with variable size population

In an epidemiological model, time spent in one compartment is often modeled by a delay in the model. In general the presence of delay in differential equations can change the stability of an equilibrium to instability and causes the appearance of oscillatory solutions. In this paper we consider a SIS epidemiological model with demographic effects: birth, mortality and mortality caused by infect...

Global Stability of Vector-Host Disease with Variable Population Size

The paper presents the vector-host disease with a variability in population. We assume, the disease is fatal and for some cases the infected individuals become susceptible. We first show the local and global stability of the disease-free equilibrium, for the case when R 0 < 1. We also show that for R 0 < 1, the disease free-equilibrium of the model is both locally as well as globally stable. Fo...

Rank-based variable selection

This note considers variable selection in the robust linear model via R-estimates. The proposed rank-based approach is a generalization of the penalized least squares estimators where we replace the least squares loss function with Jaeckel’s (1972) dispersion function. Our rank-based method is robust to outliers in the errors and has roots in traditional nonparametric statistics for simple loca...
