二分类logistic回归中纳入多少自变量合适?

2016-09-13 陶立元 赵一鸣 临床流行病学和循证医学微信号

在对临床数据的探索分析工作中,我们经常会使用多因素logistic回归分析去探索疾病的危险因素,也可以用它来做预测。但是每每在使用logistic回归分析的时候,我们都会纠结应该选哪些作为自变量呢?选多少个合适呢? 选哪些作为自变量,这个问题比较简单。一般情况下,我都是选择那些单因素分析中与因变量有关的自变量进入回归方程。但同时需要提醒,如果某些自变量从作用机制或临床经验上来看,

在对临床数据的探索分析工作中,我们经常会使用多因素logistic回归分析去探索疾病的危险因素,也可以用它来做预测。但是每每在使用logistic回归分析的时候,我们都会纠结应该选哪些作为自变量呢?选多少个合适呢?

选哪些作为自变量,这个问题比较简单。一般情况下,我都是选择那些单因素分析中与因变量有关的自变量进入回归方程。但同时需要提醒,如果某些自变量从作用机制或临床经验上来看,跟因变量之间关系密切,此时也应该将其选入方程,即使单因素分析没有意义。

选谁确定了,剩下的就是选多少个合适了。假设我们的研究对象有m个,需要选择的自变量有n个。如果此时m很大且n很小,那么一般情况都可以选进来;如果此时m相对于n不够大,则不可以盲目的将n个自变量都丢进方程。

至于m和n之间的关系,有教科书上指出:经验上病例和对照的人数应该至少各有30-50例,方程中自变量的个数越多需要的研究对象例数也越大。

1985年,Harrell等人在其研究论文中指出:从理论上来讲,多因素分析中至少需要的EPV数量为10-20个。EPV(events per variable),就是每个自变量所需要的事件数。举个例子,也就是研究对象中较少组的数量,除以自变量的个数所得到的。如果m个研究对象中有m1个人有疾病,m2个人无疾病(m1+m2=m),同时m1小于m2,此时EPV=m1/n(n为自变量个数)。

在1996年,Peter等人针对logistic回归做了计算机模拟试验,探索EPV对logistic回归结果的影响。他们基于一个真实的心血管疾病研究数据,包含673个病人,其中有252人死亡。采用随机抽样的方法,分别设定EPV为2,5,10,15,20和25,计算logistic回归结果并于原始结果比对。其研究结果指出:当EPV大于等于10的时候,回归结果比较稳定,且与原始结果较为一致。当EPV小于10时,其偏回归系数偏倚较大。

到2006年,Eric等人发表题为“放松Logistic和Cox回归中10个EPV的规则”的论文,文中指出仅仅通过几个计算机模拟试验就确定EPV≥10的规则未免太过保守。作者通过更多数据的计算机模拟,以及对更多影响因素的考虑,指出EPV≥5即可获得可接受的结果,同时EPV过小,可考虑采用bootstrap的方法进行敏感性分析。

针对这个EPV的数量应该多少合适,不同的研究有不同的观点,2009年Karel等人在BMJ发表论文时指出:EPV大于等于10时较为合适,尽管有人提出EPV可以更小。

在此小编建议,在使用logistic回归做危险因素探索的时候考虑EPV≥10,应该是足够的了。注意此处是EPV≥10,而不是m/n≥10。如果拿logistic回归结果来做预测呢?个人觉得可能需要更大的EPV。除此之外,我们还应该考虑其他的预测建模方法(如随机森林等),同时对预测模型进行严格的评价。

probit回归和logistic回归区别

probit回归和logistic回归几乎可以用于相同的数据,对于二分类因变量,这两种方法的结果十分类似。那他们到底有什么区别呢?如 果从分布角度来讲,logit函数和probit的函数几乎重叠,但反映的含义不同,logit等于p/(1-p),这里p是结局发生的概率,而 probit的函数是F-1(p),注意-1是上标。F是累积的标准正态分布函数,所以F-1就是累积标准正态分布函数的逆函数或反

似然比与logistic回归

似然,英文就是likelihood,实际上也可以翻译为可能性,翻译成“似然”可能只是为了书面听起来好听一些。最大似然也就是最大可能性,最大似然估计也就是找出一个最大可能使函数接近观测值的一个参数。通 常我们用统计软件做卡方检验时,同时会有一个似然比检验,而且二者的值极其接近。卡方检验和似然比检验其实并没有什么太大关系,更像是两条可以同时到达同 一个终点的路,至于你喜欢走哪条路,你自己选择,并没
