Considering partially linear single-index errors-in-variables model which can be described as Y = n(X T a) + ZT ßo + e when the Z' s are measured with additive errors. The general estimators established in literature are biased when ignoring the measurement errors. We proposed two estimators in...

This dissertation includes three components. Component 1 provides an estima-tion procedure for circadian parameters in cyanobacteria. Component 2 explores therelationship between baseline and amplitude by model selection under the frameworkof smoothing spline. Component 3 investigates properties...

Semiparametric models play important roles in the field of biological statistics. In this dissertation, two types of semiparametic models are to be studied. One is the partially linear model, where the parametric part is a linear function. We are to investigate the two common estimation methods...
