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...

The extent and pattern of linkage disequilibrium (LD) determine the feasibility of association studies to map genes that underlie complex traits. Here we present a statistical algorithm for constructing a joint linkage-linkage disequilibrium map by simultaneously estimating the recombination...

A test is proposed that extends the Chen-Wolfe (1990) test for umbrella alternatives with an unknown peak to use with ranked-set samples data. This follows from ideas in Bohn & Wolfe (1992), Magel (1994), and Hartlaub & Wolfe (1999). Critical values are simulated for the proposed test based on...

This paper addresses the issue of monetary policy transparency in a context of model uncertainty by adapting the robust control approach. We find that even if the desire of robustness induces an aggressive response of union and central bank, the central bank should reveal its preference about...
