This paper concerns outlier robust non-parametric regression with smoothing splines for data that are possibly correlated. We define a robust smoother as the minimizer of a penalized robustified log likelihood. Our estimation algorithm uses iteratively reweighted least squares to estimate the...

In this paper, we examine the inflation persistence puzzle by applying the robust control approach of Hansen and Sargent (2008). In line with the literature suggesting that inflation persistence may be affected by the monetary policy design and its institutional characteristics, we find that...

Ecological agriculture is the important industrial foundation for building eco-cities, while green agriculture policy plays an essential role in promoting sustainable development of ecological agriculture. This paper analyzed the relationship between green agriculture policy and developing...

With the development of modern technology, tremendous amount of data can be collected in biomedical experiments. These data can arise as curves or groups of time series, therefore it is natural to use a curve or a time series as the basic unit in the data analysis. In this dissertation, we...

Missing problem is very common in today's public health studies because of responses measured longitudinally. In this dissertation we proposed two latent variable models for longitudinal data with informative missingness. In the first approach, a latent variable model is developed for the...
