Description Usage Arguments Author(s) Examples
通过倾向性评分对样本进行1:1的matched。 支持"nonrandom","MatchIt"两种策略。
1 2 3 4 5 6 7 | pair.random(data,
contrast,
cluster,
seed = 2018,
ratio=0.2,
pair = TRUE,
summary = T)
|
contrast |
string.colnames. |
seed |
seed used in sample() |
pair |
logic.If T,give a random-matched pair data by giving a contrast |
summary |
logic.If T,give a simple data. |
