课程内容

Topic 1 Techniques for Nonparametric Models

Nonparametric regression models have been used to explore the complicated relation between the response and the predictors of interest because it may be very difficult if not impossible to give any close- form to express this relationship. I will present an up--to--date picture on the state of nonparametric regression. Several fundamental techniques such as local polynomial, smoothing spline, and penalized spline will be presented.

Topic 2 Semi-parametric Generalized Partially Linear Models

More recently a lot of efforts have been made to balance the interpretability and simplicity of para-metric models and the flexibility of nonparametric models. Important results of those efforts are semi-parametric regression models. Emphasis in this lecture is on generalized partially linear models (GPLM), in which the conditional expectation of the response variable given covariates depends on some variable in a linear way but nonlinearly related to other variable. They compro-mise the interpretation of traditional (generalized) linear models and flexibility of non-parametric regression. GPLM contain generalizations of multiple linear regression mod-els, generalized linear models, and partially linear models. This lecture will cover the methodological aspects of pro?le likelihood and back?tting in GPLM for cross--sectional and longitudinal data.

Topic 3 Generalized additive partial linear models

Concerning on the computational burden when backfitting and kernel methods are used to fit generalized additive partial linear models (GAPLM), we have made a lot of efforts for use of spline to approximate nonparametric functions and to make inference in GAPLM. This lecture will cover estimation and inference in GAPLM for cross-section and correlated data using the generalized estimating equation and quadratic inference function principles.
