R插件匹配1687对,与python匹配不一致的原因,一是δ不一样,二是因为pre产生模型R插件更优秀考虑了哑变量形式,所以不能简单的将相对系数在两个插件中直接换算。由于python插件没有考虑哑变量形式,我们可以发现python_ps与R得到的ps不一致,所以只推荐用来做个体匹配...
You can also aggregate data after reading it into IBM SPSS Statistics, but preaggregating may save time for large data sources. 1. To create aggregated data, select one or more break variables that define how cases are grouped. 2. Select one or more aggregated variables. 3. Select an ...

方法②:我们尝试python插件(绝对值δ=0.03)与R插件(δ=0.2S)同时测试,如下图。Python插件fuzzy match匹配1750对,治疗组匹配率81.4%, 仔细看输出文档会发现python插件没有考虑哑变量问题,这在无序分类变量比例高的时候会导致一定局限性,Pre计算错误。 图14 pyt...
