真实世界研究常用统计分析方法

2019-05-29 不详 网络

相较于RCT研究,真实世界研究中的因果推断需要特别注意对混杂效应的调整,因此会用到一些相对较复杂的统计模型和分析方法。这些方法既包括经典的统计方法,如传统多变量回归方法,也包括一些相对来说更加前沿和复杂的统计方法,如倾向性评分匹配方法和工具变量方法。本文件仅对这些统计方法做概括性说明,更具体的方法和应用细节见所附参考文献,也不排除未介绍方法的合理应用。1.描述性分析和非调整分析对于描述性分析,

单因素分析和多因素分析的结果不一致,咋整?

我们在做统计分析时,很多人都习惯这样的分析套路:先进行统计描述,然后做单因素分析,最后再进行多因素分析。在阅读文献时,我们也会发现,不管是一般的统计描述还是单因素分析,往往能够支持研究人员作出结论的,还是要看最终的多因素分析结果。在前期推送的内容中我们也讲过,多因素分析的目的是通过控制其它多个混杂因素的影响,找出具有独立作用的影响因素,并估计其效应大小。既然这样的话,做单因素分析还有什么用呢,

加权均数差 VS 标准化均数差

两组比较研究Meta分析ESsm 的计算是基于结果变量(反应变量)为连续性分布的比较组的均数、标准差和样本量的大小,如果纳入的研究这几个统计量都具备,且各研究的结果变量采用相同的操作,比如变量的定义相同、测量的方法相同、变量的赋值相同且为连续性变量,则可直接利用原始研究各组间比较的均数差构建效应统计量,这种效应统计量称为未标化的均差效应统计量。但在大多数情况下,纳入Meta-analysis的各研

正常值范围的估计的统计学测量

在医学科研中有时需要根据样本数据推论总体中个体值范围,其中最常用的是估计正常值范围。一、正常值范围的意义正常人体的解剖、生理、生化、心理等各种数据的波动范围称正常值范围,简称正常值。如成人白细胞总数的正常值为4000~10000个/mm3。以一定数量“正常人”为样本,观察某个或几个变量,根据所得样本数据,推论总体中变量值的范围,称正常值范围估计。一些与人体有关的外界环境如噪音强度、粉尘浓度、昆

统计建模:回归,深度学习,模型可解释性?

六年前,听一位医学统计的泰斗讲 logistic 回归,说,为什么 logistic 回归叫做logistic?经泰斗查阅浩瀚史料,原来是来自于二战时期美军后勤(logistics)运输中的统计建模。 届时百思不得:后勤情形中,建模用的因变量,如何转化为二分类? 泰斗虽犹在,小可不敢问。 logistic 曲线首创者 Verhulst 当然,本文也不

Z-Test与T-Test的深入剖析与区别

推论统计,提到假设检验,从脑海里一跃而出的便是 Z-Test 与 T-Test。可能在大学里学习时对这个两个检验方法囫囵吞枣,现在重新理解,更是疑问重重。 都知道, Z-Test 与 T-Test 用于正态分布的统计检验,大致也能知道T或Zvalue 大于查表后的某个数,便是统计显著差异,需要拒绝,百度搜索也能得知 Z-Test 与 T-Test 的区别: Z-Test 用

统计模型选择的一些基本思想和方法

引言 有监督学习是日常使用最多的建模范式,它有许多更具体的名字,比如预测模型、回归模型、分类模型或者分类器。这些名字或来源统计,或来源于机器学习。关于统计学习与机器学习的区别已经有不少讨论,不少人认为机器学习侧重于目标预测,而统计学习侧重于机制理解和建模。个人更加直观的理解是,统计学习侧重于从概率分布来描述数据生成机制,除了预测之外,还关心结果(参数假设、误差分布假设)的检验,而机器学习侧重
