I am using the MatchIt package to perform matching between two groups (obese and not obese). The dataset that I am using has no missing data. I am matching on age, sex, and race.

A practical guide to use -matchit- (1) ssc install matchit // only if not installed already use file1.dta matchit id1 txt1 using file2.dta, idu(id2) txtu(txt2) br // if you want to manually check results gsort -similscore // if you want to use other variables to disambiguate results joinby id1 using file1 joinby id2 using file2 Code: . matchit idfocal focal using licensor.dta, idusing (idlicensor) txtusing (licensor) The above command is the simplest form of the command (2-gram parsing): This is strange because the score of the first matching is 0.577 while the score of the last matching (a correct matching) is 0.538. 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. Hello, I came across your matchit command in Stata for data consolidation and cleaning using fuzzy string comparisons.

Which of the following two parameters of the matchit function that are related to the Mahalanobis distance should I use: the distance="mahalanobis" param, or; the mahvars param (e.g., mahvars = c("X1", "X2")?

Raffo Senior Economic MATCHIT: Stata module to match two datasets based on similar text patterns.

Merge datasets by partially matching key variables in Stata I work with messy administrative data and very often have to merge datasets by people’s or cities’ names. String variables often come with typos, different spelling, etc.

matchit is the main function of MatchIt and performs pairing, subset selection, and subclassification with the aim of creating treatment and control groups balanced on included covariates. MatchIt implements the suggestions of Ho, Imai, King, and Stuart (2007) for improving parametric statistical models by preprocessing data with nonparametric matching methods.

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.

Messages sorted by: [ date ] [ thread ] [ subject ] [ author ] I read too much into the question--I thought Casey was asking about complex survey data --sorry. 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 .

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. Statistical Software Components. 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.

Here is a 'hack' using the community-contributed command matchit to produce the desired output: local obs = _N generate Cont = 0 forvalues i = 1 / `obs' { forvalues j = 1 / `obs' { replace Cont = 1 if Brand_1 [`i'] == Brand_2 [`j'] in `i' generate b1 = Brand_1 [`i'] in 1 generate b2 = Brand_2 [`j'] in 1 matchit …

Yes, all those which are above the threshold you select (or default) based on the cross grams from both master and using files. How to get a full list is the matter of your other post and you can find a sample code there.
