Evaluating the effect of city lock-down on controlling COVID-19 propagation through deep learning and network science models
Xiaoqi Zhang, Zheng Ji, Yanqiao Zheng +2
The special epistemic characteristics of the COVID-19, such as the long incubation period and the infection through asymptomatic cases, put severe challenge to the containment of i…
A novel approach to estimate the Cox model with temporal covariates and its application to medical cost data
Xiaoqi Zhang, Xiaobing Zhao, Yanqiao Zheng
We propose a novel approach to estimate the Cox model with temporal covariates. Our new approach treats the temporal covariates as arising from a longitudinal process which is mode…
Insert "Price" to Coxian Phase-Type Models: An Application to Hospital Charge and Length of Stay Data
Yanqiao Zheng, Xiaoqi Zhang
In this paper, we discuss the connection between the RGRST models (Gardiner et al 2002, Polverejan et al 2003) and the Coxian Phase-Type (CPH) models (Marshall et al 2007, Tang 201…
Stochastic Process and Health Data: A Full Maximum Likelihood Method to Hospital Charge and Length of Stay Data
Xiaoqi Zhang, John Ringland
We extend the model used in Gardiner et al. (2002) and Polverejan et al. (2003) through deriving an explicit expression for the joint probability density function of hospital charg…
