General exact matching, as implemented in MatchIt, allows one-to-many matches, so to see the same result we must weight when adjusting. In other words: weighted regression adjustment after general exact matching gives the identical answer as a simple, unadjusted weighted difference in means. Opening and saving datasets in Stata works similarly to those tasks in other computer applications. There are a few differences, however. First, it is possible to save and open ﬁles from within Stata’s Command window. Second, Stata allows just one dataset to be active at any one time. That is, while it Stata cannot calculate the statistic you requested using weighted data.

Other uses of -matchit- -matchit-can also be applied to two variables of the same dataset This can also be applied as an alternative to indexation -freqindex-(included with -matchit-) can be used to generate “bag of words” or custom weight files All functions (similarity, score or weights) can be easily customized by users use file1.dta matchit is a tool to join observations from two datasets based on string variables which do not necessarily need to be exactly the same. It performs many different string-based matching techniques, allowing for a fuzzy similarity between the two different text variables. .

This technique matches each treated unit to all possible control units with exactly the same values on all the covariates, forming subclasses such that within each subclass all units (treatment and control) have the same covariate values. Exact matching is implemented in MATCHIT using method = "exact".

I'll read up on the procedure before I Matching the Exact Matching of MatchIt. I started a series on causal inference for data science a few weeks back. I think CI methodologies offer great potential for the DS discipline, given that much of our data is observational i.e. outside experimental control.

Stata resources are included with the linked paper. 2020-05-28 MatchIt implements the suggestions of Ho, Imai, King, and Stuart (2007) for improving parametric statistical models by preprocessing data with nonparametric matching methods. MatchIt implements a wide range of sophisticated matching methods, making it possible to greatly reduce the dependence of causal inferences on hard-to-justify, but commonly made, statistical modeling assumptions.

Usually when you merge, you have a unique ID — or at least enough of one that you can salvage.Sometimes, however, no unique identifier was collected, and you’re left searching for alternative ways to link two datasets.

matchit 可以对同一数据集中的两列数据进行相似度匹配，其基本语法如下： matchit varname1varname2 [, options ] 其中， varname1 和 varname2 是所选的进行匹配的两个列的变量名，还可以设置一些选项对匹配结果进行适当约束。 5th Polish Stata Users Meeting, Warsaw, 27th November 2017 Research ﬁnanced under National Science Center, Poland grant 2015/19/B/HS4/03231 numeric variable, in MS Excel and in STATA .
