COVID-19: Short term prediction model using daily incidence data

PLoS ONE · 2021 · 54 citations

BACKGROUND: Prediction of the dynamics of new SARS-CoV-2 infections during the current COVID-19 pandemic is critical for public health planning of efficient health care allocation and monitoring the effects of policy interventions. We describe a new approach that forecasts the number of incident cases in the near future given past occurrences using only a small number of assumptions. METHODS: Our approach to forecasting future COVID-19 cases involves 1) modeling the observed incidence cases usin…

Park Characteristics and Changes in Park Visitation before, during, and after COVID-19 Shelter-in-Place Order

Sustainability · 2022 · 22 citations

The COVID-19 pandemic has limited people’s visitation to public places because of social distancing and shelter-in-place orders. According to Google’s community mobility reports, some countries showed a decrease in park visitation during the pandemic, while others showed an increase. Although government responses played a significant role in this variation, little is known about park visitation changes and the park attributes that are associated with these changes. Therefore, we aimed to examine…

Bayesian Spatial Homogeneity Pursuit of Functional Data: An Application to the U.S. Income Distribution

Bayesian Analysis · 2022-06-17 · 22 citations

An income distribution describes how an entity’s total wealth is distributed amongst its population. A problem of interest to regional economics researchers is to understand the spatial homogeneity of income distributions among different regions. In economics, the Lorenz curve is a well-known functional representation of income distribution. In this article, we propose a mixture of finite mixtures (MFM) model as well as a Markov random field constrained mixture of finite mixtures (MRFC-MFM) mode…
