Lu, Wenhua (2014-08-13)Previous research on children’s active commuting to school (ACS) focused mainly on physical and social environmental predictors of the behavior, leaving psychological factors under studied. The purpose of this dissertation ...
-
Ren, Haobo (Texas A&M University, 2006-10-30)The basic philosophy of Functional Data Analysis (FDA) is to think of the observed data functions as elements of a possibly infinite-dimensional function space. Most of the current research topics on FDA focus on advancing ...
-
Jin, Lei (2009-05-15)In this dissertation, the generalized score tests based on weighted estimating equations are proposed for missing covariate data. Their properties, including the effects of nuisance functions on the forms of the test ...
