内容简介：In this talk, I will present several semi-parametric
models including partial linear additive models and generalized partial linear
additive models, which can relax structure assumption for linear or generalized
linear models, and briefly mention the associated methods we have developed. I
will elucidate them by using several real datasets to show why semi-parametric
models are helpful and useful in health science and biomedical research. Examples include a nutritional epidemiology
study for exploring the relationship between
plasma beta-carotene levels and personal characteristics and dietary factors, a
HIV/AIDS study of the relationship between the use of condom and other indexes such as CD4 cell count and
marital status, whether diabetes disease is related to BMI and age. Finally I
will show you how to explore the relationship between cancer and genes when the
number of gene expressions is larger than the number of subjects.
