Verification results for age-structured models of economic-epidemics dynamics.

Giorgio Fabbri, Fausto Gozzi, Giovanni Zanco · 2021

In this paper we propose a macro-dynamic age-structured set-up for the analysis of epidemics/economic dynamics in continuous time. The resulting optimal control problem is reformulated in an infinite …

New approximations, and policy implications, from a delayed dynamic model of a fast pandemic.

C P Vyasarayani, Anindya Chatterjee · 2020

We study an SEIQR (Susceptible-Exposed-Infectious-Quarantined-Recovered) model due to Young et al. (2019) for an infectious disease, with time delays for latency and an asymptomatic phase. For fast pa…

Allowing for correlations between correlations in random-effects meta-analysis of correlation matrices.

 · 1970

Practical meta-analysis of correlation matrices generally ignores covariances (and hence correlations) between correlation estimates. The authors consider various methods for allowing for covariances,…
