| 摘 要： | 应用列联表方法研究化石群落间的关联性问题。列联表方法是从变量的独立性出发研究两两变量间的关系。该方法的优，或是不但能用数字表示两变量间的关联程度，而且还对其关联性作显著性检验，使所得结果更为精确。本文介绍的数学原理和计算方法，力求简明易懂。最后选择了实际例子借以说明列联表方法在研究此问题上的良好效果。

| Abstract: | The topie of this thesis is about how to apply the contingeney table tore search for associability of fossil- community.Proceeding from indcpendence ofvariable,contingeney table niethod studies the relationship of variables. The advantagesof this method not only displays level of assoeiability between variables, but also does thetest of significiance of associability. So make the result preeiser. The author introduce the mathematical principle and the calculating method ofContingency table briefly;meamwhile try an effort to makle it very simple and easy.At the end,the writer choose tho factual examplc to dcmonstrate the good eftects ofContingeney table method. |
