如何通过SPSS软件实现随机化过程?

2015-08-16 陶立元 赵一鸣 临床流行病学和循证医学

随机过程是临床研究过程中至关重要的一部分。在前面的内容中我们也讲过了很多关于随机和随机数的内容,请大家参阅旧的目录。本期将跟大家一起讨论一下如何通过SPSS来实现随机化过程。 在说之前,先跟大家聊一聊随机数的类型,随机数有真随机数(True Random Number)和伪随机数(Pseudo Random Number)之分。我们平时所使用的无论什么程序产生的随机数都是伪随机数,它是有“种

随机过程是临床研究过程中至关重要的一部分。在前面的内容中我们也讲过了很多关于随机和随机数的内容,请大家参阅旧的目录。本期将跟大家一起讨论一下如何通过SPSS来实现随机化过程。 在说之前,先跟大家聊一聊随机数的类型,随机数有真随机数(True Random Number)和伪随机数(Pseudo Random Number)之分。我们平时所使用的无论什么程序产生的随机数都是伪随机数,它是有“种子”的,种子决定了随机数的固定序列。而真随机数很多情况下只能看老天的眼色,比如掷骰子、布朗运动、量子效应、放射性衰变等等,所以说我们在临床研究中常用的软件产生随机数的方法都是伪随机数,伪随机数虽然不具有完全的随机性,但是已经足够用了。 总体上SPSS为随机化提供了两类过程,第一类过程直接进行随机抽样或分组,第二类过程只生成随机数字,需要研究者依据随机数字自己去进行随机抽样或分组。 在上述过程中,我们都可以选择采用“随机种子数”或“固定种子数”两种方式来产生随机数。采用“随机种子数”时,随机数字不可重现;采用“固定种子数”时,随机数字可以重现出来。由于SPSS的syntax不是所有人都常用,在此就不说

倾向得分分析---临床研究中的利器(SPSS操作演示)

关于因果分析的四种前沿统计方法:样本选择模型,倾向值匹配(Propensity Score Matching, PSM)方法,匹配估计量,基于内核的匹配法。 随机对照实验(RCT)有很多限制,如费用、伦理学要求、操作困难、不适合发病率很低的疾病;非随机对照实验(RCT)可以避免以上繁杂的问题,但容易组间基线不齐,使之成为处理效应的混杂因素,从而产生偏倚。解决方法一般是使用多变量分析模

SPSS软件应用:两指标间的关系分析

两个变量之间存在一次方函数关系,就称它们之间存在线性关系。临床医学统计中有三种主要的线性关系:线性相关(Pearson相关)、秩相关(Spearman相关)和曲线相关(曲线拟合)。本文结合临床实际案例讲述如何使用SPSS软件分析两指标间的关系。一、线性相关线性相关是最常见的相关分析,也叫做Pearson相关分析。定性资料相关:当一个变量增大,另一个变量也随之增大,称为共变或相关。两个变量有共变现象

SPSS软件应用——线性回归分析操作及演示图

“回归”,最早由英国遗传学家弗朗西斯•高尔顿(Francis Galton)引入。在一篇著名的论文“Family Likeness in Stature”中,高尔顿发现,虽然有一个趋势:父母高,子女也高;父母矮,子女也矮,即父母的身高对子女的身高起到决定性作用。但给定父母的身高,子女的平均身高却趋向于或者“回归”到种族人群的平均身高。换言之,尽管父母都非常高或非常矮,但儿女的身高却有回归到人群总体

SPSS软件应用:重复测量数据的统计方法

重复测量设计,即对一组或多组受试对象,在k个(k≥2)不同的时间点上,从每个人体(或样本)上重复观测同一个指标的具体取值的设计。如临床研究中,需要观察患者在不同时间的某些生理、生化或病理指标的变化趋势,或治疗干预后不同时间或疗程的疗效特点,就要进行重复测量设计。重复测量数据间存在相关性,不符合方差分析要求,所以重复测量数据资料需要采用专门的统计分析方法,该方法也是近代统计学研究的热点之一。对于重复

SPSS带你玩转GLM方差分析,一学就会!​

方差分析(Analysis of Variance,简称ANOVA),又称“变异数分析”或“F检验”,是R.A.Fisher发明的,用于两个及两个以上样本均数差别的显著性检验。它是以F值为统计量的计量资料的假设检验方法。检验方法是将总方差分解成两个或多个部分方差和,推断两组或多组的总体无数是否相等。原假设H0:多个试验组的总体均数相等,即处理因素无作用。检验水准:ɑ=0.05。GL
