问题的提出 1、计量经济学模型,需要经常考虑属性因素的影响。例如,职业、战争与和平、繁荣与萧条、文化程度、灾害、季节 2、属性因素往往很难直接度量它们的大小。只能给出它们的“Yes—D=1”或”No一D=0”、或者它们的程度或等级

A point at which two or more elements have common connection is called node(节点). Suppose that we start at one node in a network and move through a simple element to the node at the other..., if no node was encountered more than once, then the set of nodes and elements that we have passed hrough is defined as path(路径)
