In other words: weighted regression adjustment after general exact matching gives the identical answer as a simple, unadjusted weighted difference in means. 2016-05-07 Next message: [matchit] which Stata weight to use? Messages sorted by: I read too much into the question--I thought Casey was asking about complex survey data --sorry. I read into his question something I've been thinking about for another project. 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.

Introduction and motivation Matching Numerical examples Final Outline 1 Introduction and motivation Hi Veeresh, I'm sure other Stata users will suggest better solutions. However, it is simple to convert to lower case for one or more vars. For example, I just wrote the following loop in which title is the string variable(s): local title title foreach var of varlist title{ gen title1=lower(`var') } Hope this helps, Dr Tim King Leeds University Business School _____ From: owner-statalist I am using MatchIt library in R. I ran the model successfully but I am not able to interpret the output.

The dataset that I am using has no missing data. I am matching on age, sex, and race.

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 …

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 Hi Statalisters, I try to use fuzzy match commands matchit and reclink to merge two datasets. Here is an example of master file.

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.
