On the research of region difference and time factor in residents consume behavior,we makes use of the more general form to the longitudinal data analysis,dynamic linear mixed models,to build this model,and discusses the characters of estimation of dynamic linear mixed models under the situations of the fixed effect models.

Secondly, a semi-automatic image annotation method based on auxiliary tags isproposed, which measures the relevance between tags by the normalized mutual information,and improve the tag classification with a dynamic mixture model.

Results The reasonable results were obtained for repeated measurements in single-sample by the methods of mixed linear model.

Monte Carlo simulation combining with mixed linear model were used in the research of evaluating parameters for rice core collection based on genotypic values and molecular marker information, which eliminated the interference of environment and obtained more reliable results.

Two criteria for the measures of genetic connectedness in mixed linear model of genetic evaluation are used： the degree of connectedness（ IC） and the generalized coefficient of determination (CD).

Test of variance components of linear mixed model;

The Research of Endmember Extraction Approaches from Hyperspectral Image Based on the Linear Mixed Model;

Methods To apply linear mixed models to the nuclear family data, to set up the genetic variance component model in term of familial genetic relationship, and to estimate parameters by WinBUGS and the PROC Mixed in SAS in order to analyze the effects of risk factors.
