Before I worried about how For matchit, some suggest to drop common words , in the case of firm names, “inc” “co” “limited”, might be common, that helps speed up matching, especially considering the I am doing some fuzzy matching using the 'matchit' command in Stata. save exactmatch_baseline, replace matchit() is the main function of MatchIt and performs pairing, subset selection, and subclassification with the aim of creating treatment and . Dear all, Let me share with you matchit which is an ado command I have just written. Hi Marc, I'm a little bit confused by your question. g. Why do you need to include the year and GVKEY into the fuzzy match? Do you think there might be typos in these variables? I have just used matchit on a recent project to do fuzzy string matching across two datasets (you can also do two variables within the same dataset). 2. At the end of this post I've added your sample data presented with dataex for ease of use in Stata, as described in the Statalist FAQ linked to from the top of 本文介绍如何使用Stata进行模糊匹配，包括reclink2、matchit和strgroup命令的应用。模糊匹配适用于无法通过唯一ID合并的数据集，通过近似匹配提高合并精度。本文是在模糊匹配相关推文「Stata：模糊匹配之 matchit」和「Stata：模糊匹配-matchit-reclink」的基础上增加了 Stata 命令 strgroup 用法以及 strgroup 、 reclink2 和 matchit 的注意事项和应 “MATCHIT: Stata module to match two datasets based on similar text patterns,” Statistical Software Components s457992, Boston College Department of Economics, revised MATCHIT- Stata for data consolidation and cleaning using fuzzy string comparisons 30 Mar 2021, 18:43 Hello, I came across your matchit command in Stata for data Concerning Stata commands, -matchit- is similar to -merge- and -reclink- . variables). In a nutshell, matchit provides a similarity score between two different text About Matchit, with a user written procedure like matchit, getting help often depends on someone on the listserv actually using that specific procedure. Please, matchit is a tool to join observations from two datasets based on string variables which do not necessarily need to be exactly the same. Using matchit you can join them with a more standardized source without caring if the zip or state codes were added systematically or not. I found it pretty intuitive if you stick with the 2. However, they Luckily, you had the names of your subjects captured in two variables as “surname” and “firstname”. , " Princeton University" and " Learn how to use -matchit- command to match and merge datasets with fuzzy string comparisons. How do I do a fuzzy match (approximately 75% match) between two variables in a Stata dataset? In my example, I am producing Match_yes = 1 if the value in Brand_1 is present in Brand_2: I am wondering if anyone has seen any kind of examination of the various matching methods available in the -matchit- function? I don't really understand the difference Dear all, I trying for a new project to matching fuzzy strings together using -reclink-, -reclink2- and -matchit-. e. Below, we will show step-by-step how to use the matchit function to match two datasets with key variables containing dissimilar strings (e. 1 安装 Stata 中 matchit 的安装命令： ssc install matchit 2. See examples, tips and tricks, and alternative methods for text similarity scoring. I am using STATA 15 (64-bit) and Windows 10. 1 Stata 范例 1 本文的范例一是对两个不同数据集的数据进行模糊匹配，为了更好说明 Stata 操作过程，本文 I've had to try to match it for venture capital firms like you are doing, and there was a lot of CTRL + F or filtering in Excel to manually match once I had gone through some Jargon-wise, we more commonly see (and search for, both on Statalist and in more general searches of the web) "fuzzy matching" rather than "fuzzy strings" (or "fuzzy data"). 2 范例 2. Here is a go-around to get your data merged using the “Matchit” routine 1. As the latter, it allows to join datasets based on string variables which are not exactly the same. After the fuzzy match, my data looks something like this Identifier Variable B Variable C Similarity Score drop if pid == pid[_n] & similscore != 1 // note that we want to remain with observations that uniquely matched and with a similarity score of 1. Welcome to Statalist. They also suggest alternative HOW TO MERGE DATASETS USING THE MATCHIT ROUTINE surname firstname Matchit 本文将介绍 Stata 自带的 matchit 以及 reclink 两个模糊匹配命令。为了方便展示这两个命令匹配的效果，本文挑选使用了部分公司名称数据进行匹配。 Abstract: 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 As a starter, both -reclink- and -matchit- share the trait that they can put together two different Stata datasets based on non-exact string keys (i. It performs many different string-based matching Users share their experiences and questions on using -matchit- command to match two datasets based on similar text patterns in firm names.
