A nomogram is a graphical representation of a mathematical model involving several pre- dictors to predict a particular endpoint based on traditional statistical methods such as Cox proportional hazards model for survival data or logistic regression for binary outcome。
From a network perspective， health behaviours and outcomes can be conceptualised as emergent phenomena from a system of reciprocal interactions: network analysis offers a powerful methodological approach to investigate the complex patterns of such relationships.

In the first step， the dataset with missing values is copied several times. Then in the next step， the missing values are replaced with imputed values in each copy of the dataset. In each copy， slightly different values are imputed due to random variation. This results in mulitple imputed datasets. In the third step， the imputed datasets are each analyzed and the study results are then pooled into the final study result.
元旦前在人民日报中央厨房上看到一篇文章，叫做“比肩辉瑞的国产新冠药物VV116，是这样研制和临床试验的”，想来就把文献原文找来读了读，写下本文分享给大家，本文主要关注文章的正文中主要统计设计，前面的实验设计，包括盲法，纳排标准统统不在本文考虑，主要目的是让大家感受下NEJM的杂志的统计做法到底有多“难”。
比如我现在需要训练一个logistics模型，我就可以写出如下代码:在上面的代码中，我们设定了4个重要的参数:一是模型公式form，二是数据来源data，三是交叉验证方法，这儿我们使用的是5折交叉验证，四是模型算法method。
