用SPSS进行列联表分析(Crosstabs)实例

2010-12-18 MedSci原创 MedSci原创

列联表分析(Crosstabs) 列联表是指两个或多个分类变量各水平的频数分布表,又称频数交叉表。SPSS的Crosstabs过程,为二维或高维列联表分析提供了22种检验和相关性度量方法。其中卡方检验是分析列联表资料常用的假设检验方法。例子:山东烟台地区病虫测报站预测一代玉米螟卵高峰期。预报发生期y为3级(1级为6月20日前,2级为6月21-25日,3级为6月25日后);预报因子5月份平均气温x

列联表是指两个或多个分类变量各水平的频数分布表,又称频数交叉表。SPSS的Crosstabs过程,为二维或高维列联表分析提供了22种检验和相关性度量方法。其中卡方检验是分析列联表资料常用的假设检验方法。
例子:山东烟台地区病虫测报站预测一代玉米螟卵高峰期。预报发生期y为3级(1级为6月20日前,2级为6月21-25日,3级为6月25日后);预报因子5月份平均气温x1(℃)分为3级(1级为16.5℃以下,2级为16.6-17.8℃,3级为17.8℃以上),6月上旬平均气温x2(℃)分为3级(1级为20℃以下,2级为20.1-21.5℃,3级为21.5℃以上),6月上旬降雨量x3(mm)分为3级(1级为15mm以下,2级为 15.1-30mm,3级为30mm以上),6月中旬降雨量x4(mm)分为3级(1级为29mm以下,2级为29.1-36mm,3级为36mm以上)。数据如下表。

1) 输入分析数据

在数据编辑器窗口打开“data1-3.sav”数据文件。

数据文件中变量格式如下:

 

2) 调用分析过程

在菜单选中“Analyze-Descriptive- Crosstabs”命令,弹出列联表分析对话框,如下图

 

3) 设置分析变量

选择行变量:将“五月气温[x1],六月上气温[x2],六月上降雨[x3],六月中降雨[x4]”变量选入“Rows:”行变量框中。

选择列变量:将“玉米螟卵高峰发生期[y]”变量选入 “Columns:”列变量框中。

 

4) 输出条形图和频数分布表

    Display clustered bar charts: 选中显示复式条形图。

    (其余的省约)

    结果分析:

    从交叉表(Crosstab)对角线中看出,只有“五月气温与玉米螟卵高峰发生期”对角线上出现的频数大于期望值(5>2.7,3>2.0,3>1.3)。

    从卡方检验表得知,也只有“五月气温与玉米螟卵高峰发生期”能通过线性间的联合检验(Linear-by-Linear Association),双尾检验p<0.012。

    因此,玉米螟卵高峰发生期与五月气温有密切的关系,五月气温越高,发生越早。

用SPSS进行逐步回归分析实例

逐步回归分析 在自变量很多时,其中有的因素可能对应变量的影响不是很大,而且x之间可能不完全相互独立的,可能有种种互作关系。在这种情况下可用逐步回归分析,进行x因子的筛选,这样建立的多元回归模型预测效果会更较好。 逐步回归分析,首先要建立因变量y与自变量x之间的总回归方程,再对总的方程及每—个自变量进行假设检验。当总的方程不显著时,表明该多元回归方程线性关系不成立;而当某—个自变量对y影响不显著

用SPSS进行多元回归分析实例

多元回归分析 在大多数的实际问题中,影响因变量的因素不是一个而是多个,我们称这类回问题为多元回归分析。可以建立因变量y与各自变量xj(j=1,2,3,…,n)之间的多元线性回归模型: 其中:b0是回归常数;bk(k=1,2,3,…,n)是回归参数;e是随机误差。 多元回归在病虫预报中的应用实例: 某地区病虫测报站用相关系数法选取了以下4个预报因子;x1为最多连续10天诱蛾量(头);x2

非线性回归分析 在回归分析中,当自变量和因变量间的关系不能简单地表示为线性方程,或者不能表示为可化为线性方程的时侯,可采用非线性估计来建立回归模型。 SPSS提供了非线性回归“Nonlinear”过程,下面就以实例来介绍非线性拟合“Nonlinear”过程的基本步骤和使用方法。 应用实例 研究了南美斑潜蝇幼虫在不同温度条件下的发育速率,得到试验数据如下: 表5-1 南美斑潜蝇幼虫在不同
