We can use the models to study the data from regions which with spatial dependence. We discuss maximum likelihood estimation(MLE) for the model and the methods of test based on MLE. We also give some results of spatial autoregression models for the fifteen cities of Yangtze River Delta.展开更多
本文对我国企业信息化建设常见质量问题进行了分析和归纳，针对其根本、共性的原因进行研究，提出了基于A（Enterprise Architecture，企业架构）P（softwareDeve-lopment Process Management，软件过程控制）P（Busiliess Process Mari...本文对我国企业信息化建设常见质量问题进行了分析和归纳，针对其根本、共性的原因进行研究，提出了基于A（Enterprise Architecture，企业架构）P（softwareDeve-lopment Process Management，软件过程控制）P（Busiliess Process Mariagement，业务流程管理）的企业信息化建设过程框架，旨在提升企业信息化效率，并营造良性的企业IT生态。研究表明，基于APP的企业信息化建设过程框架，对企业流程管理、IT架构和信息系统软件过程控制的有效整合，将为企业的信息化建设质量和效果提供全面的保证。展开更多
