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.

Syntax. Data in two columns in the same dataset.

For my first analysis, I used the MatchIt package (see code below) to match treatment and control groups and to compare outcomes for the treated vs control. The Treat variable is 0 or 1. nn_match <- matchit (treat ~ cov1 + cov2+ cov3 , method = "nearest", data = df) In my second analysis, I'd like to assess the effect of different treatment

I'm new to R, and Im using matchit to match patients by propensity scores. My dataset includes two groups of patients that differ by whether or not they received a drug. As well as matching on propensity score, I also want to exact match on age, gender and family practice, as the decision to treat does vary significantly depending on these characteristics.

Think about languages that use diacritical marks and you have a complete mess.

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.

matchit provides a similarity score between two different text strings by performing many different string-based matching techniques. It returns a new numeric variable (similscore) containing the similarity score, which ranges from 0 to 1.

matchit has multiple matching algorithms that are explained in the helpfile. All of these provide more than one likely match, which can be used to determine a second best guess. The results from matchit can be merged by joinby or merge to the using or master datasets, but matchit does not function like a merge. This is useful for most workflows. 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.
