有序回归的SPSS分析与解释

2017-05-30 MedSci MedSci原创

等级回归分析对应的英文为“ordinal regression”,也称有序回归,以等级变量做因变量建立模型来预测危险发生的概率,因变量中各个类别要按不同程度的顺序取值。 第一步:调用界面:分析---回归---有序 选择变量做因变量、因子、协变量。 通过频数描述知,等级越高,概率即数目越多,所以选则“补充对数-对数”即complementary log-

等级回归分析对应的英文为“ordinal regression”,也称有序回归,以等级变量做因变量建立模型来预测危险发生的概率,因变量中各个类别要按不同程度的顺序取值。


第一步:在SPSS中调用界面:分析---回归---有序
spss教程:回归分析-good:[1]等级回归

选择变量做因变量、因子、协变量。

通过频数描述知,等级越高,概率即数目越多,所以选则“补充对数-对数”即complementary log-log。

其中不少知识在以前的文章讲到过的。

单元格信息:最好不要选择,因信息太多,表格输出太大而无法显示。

平行性检验:检验因变量中各类别的斜率是否相等即各类别的参数是否相同,此选项仅对有位置分量Location component)的模型有效。

“估计响应概率”:“模型估计出的观察单位属于因变量中类别的概率”。

包含多项常量”:“实际似然比值,含常数项”。

位置”:“默认的是主效应模型”。

度量”:“定义模型中的标度分量”,所选择的变量必须是位置分量所选的变量中的一部分,设置标度分量的目的是改善模型,否则没必要做选择,此处不做选择。

结果解释:

由于数据量很大,图片只是一部分的截图。

注意观察警告的情况,便于正确理解结果,比如下面的“拟合度”中的显著性,不少数据都是缺失的,有时两种检验的显著性可能不一样,就是因为太多数据缺失造成的。

spss教程:回归分析-good:[1]等级回归


“模型拟合信息”:显著性的计算概率可知,小于显著性水平0.05。

“案例处理摘要”:对原始数据的初步统计分析,表格形式如同频数描述一样。

“伪R方”:值越大,模型拟合的越好。

“拟合度”:显著性值越大,说明拟合的越好。有时因为数据缺失,“伪R方”比“拟合度”更有意义。

spss教程:回归分析-good:[1]等级回归

“参数估计值”:通过观察显著性P值,看出变量的显著性,P值大的变量说明不显著剔除掉,或者重新选择模型。

平行线检验”:由显著性概率知,斜率相同。

最后的预测类别,预测类别概率,实际类别概率都保存在数据窗口中。

如果平行线检验时,P值非常小,可能有2个原因:
(1)连接函数选择不准确。解决方法:在Options子对话框的最下方就是link下拉列表,可以选择以上5种连接函数,通过不同的连接函数选择消除该效应。
(2)系数的确在随着分割点发生变化。解决方法:使用无序多分类的Logistic回归分析multinomial logistic

有序多分类Logistic回归SPSS实战操作教程

1、问题与数据 在某胃癌筛查项目中,研究者想了解首诊胃癌分期(Stage)与患者的经济水平的关系,以确定胃癌筛查的重点人群。为了避免性别因素对结论的混杂影响,研究者将性别(Sex)也纳入分析(本例仅为举例说明如何进行软件操作,实际研究中需控制的混杂因素可以更多)。研究者将所有筛查人群的结果如表1,变量赋值如表2。 表1. 原始数据 表2. 变量赋值情况 2、对数据结构的分析

广义估计方程(GEE)的SPSS操作教程

在临床研究中,经常会比较两种治疗方式对患者结局的影响,并且多次测量结局。例如,为了研究两种降压药物对血压的控制效果是否存在差异,研究者会对两个人群服药后在不同时间点记录血压值,然后评价降压效果。或者对两组动物分别施加两种干预,连续记录多个时间点的结局,然后比较两种干预的效果。 这种设计可以用如下示意图表示: 另外,有时研究只需要收集一个时间点的数据,但是一个研究对象会提供多个部位的数据

岭回归分析原理及其SPSS实现方法

岭回归分析(RidgeRegression)是一种改良的最小二乘估计方法,它是用于解决在线性回归分析中自变量存在共线性的问题。什么?共线性是什么?共线性就是指自变量之间存在一种完全或良好的线性关系,进而导致自变量相关矩阵之行列式近似为0,导致最小二乘估计失效。此时统计学家就引入了k个单位阵(I),使得回归系数可估计。设么?没看懂,那就算了。知道岭回归分析就是用来解决多重共线性的问题,就够了。在医学

深入吃透主成分分析原理:三种不同分析策略对比

评价一个主体的指标越多,我们就多一个角度去考察它,但是指标多了之后也会有另外一个麻烦,就是如何综合使用它们来评价主体呢?排名是生活中常见的事情,但一般情况下我们只知道最终的排名结果和排名参考指标,具体的排名算法我们并不清楚,今天我们将通过SPSS软件对排名问题进行研究,以探讨其潜在的逻辑!首先导入我们得到的源数据,数据中包含排名、高校名称以及6个供参考的指标数值。有一点我们可以确定,那就是这个最终

更优尺度回归(CATREG)的SPSS分析

1、什么是最优尺度回归?英文简称CATREG,也称分类回归。 普通线性回归对数据的要求十分严格,当遇到分类变量时,线性回归无法准确地反映分类变量不同取值的距离,比如性别变量,男性和女性本身是平级的,没有大小、顺序、趋势区分,若直接纳入线性回归模型,则可能会失去自身的意义。最优尺度回归就是为了解决类似问题,它擅长将分类变量不同取值进行量化处理,从而将分类变量转换为数值型进行统计分析。可以说有了最优尺

在SPSS软件中实现1:1倾向性评分匹配(PSM)分析

谈起临床研究,如何设立一个靠谱的对照,有时候成为整个研究成败的关键。对照设立的一个非常重要的原则就是可比性,简单说就是对照组除了研究因素外,其他的因素应该尽可能和试验组保持一致,这里就不得不提随机对照试验。众所周知,随机对照试验中研究对象是否接受干预是随机的,这就保证了组间其他混杂因素均衡可比。 但是有些时候并不能实现随机化,比如说观察性研究。这时候倾向性评分匹配(propensit
