A semiparametric spatial dynamic model
Yan Sun, Hongjia Yan, Wenyang Zhang +1
Stimulated by the Boston house price data, in this paper, we propose a semiparametric spatial dynamic model, which extends the ordinary spatial autoregressive models to accommodate…
A Normal Hierarchical Model and Minimum Contrast Estimation for Random Intervals
Yan Sun, Dan Ralescu
Many statistical data are imprecise due to factors such as measurement errors, computation errors, and lack of information. In such cases, data are better represented by intervals…
A semiparametric model for cluster data
Wenyang Zhang, Jianqing Fan, Yan Sun
In the analysis of cluster data, the regression coefficients are frequently assumed to be the same across all clusters. This hampers the ability to study the varying impacts of fac…
Estimation of the covariance matrix of random effects in longitudinal studies
Yan Sun, Wenyang Zhang, Howell Tong
Longitudinal studies are often conducted to explore the cohort and age effects in many scientific areas. The within cluster correlation structure plays a very important role in lon…
