Matching with R
November 16 @ 2:00 pm - 4:00 pm
Rackham Building, Earl Lewis Room, 3rd Floor East
An introduction to matching, such as propensity score matching, using R‘s “optmatch” package. Matching is used to improve balance between groups, typically in observational studies, by creating quasi-experimental strata of similar individuals. We will discuss the theory behind matching and propensity scores, followed by examples using R to perform the matching and judging the match quality, as well as speeding up the matching operation. Basic familiarity with R will be assumed.
