Match on an outcome-adaptive lasso propensity score

Source: R/handoff.R
oal_match.Rd

Convenience pass-through to MatchIt::matchit(): matches on the propensity score of an oal() fit, reusing the formula and data stored in the object. Equivalent to the canonical explicit call

MatchIt::matchit(<formula>, data = <data>, distance = fit$ps, ...)

but with no opportunity for row misalignment between the two steps. All ... arguments are forwarded verbatim; the return value is an ordinary matchit object, so the full MatchIt/cobalt toolkit applies.

Usage

oal_match(object, ...)

Arguments

object

An oal object.

...

Arguments forwarded verbatim to MatchIt::matchit() (e.g., method, caliper, ratio, replace).

Value

A matchit object; see MatchIt::matchit().

Examples

data("lalonde", package = "MatchIt")
fit <- oal(treat ~ age + educ + married + re74, data = lalonde,
           outcome = ~ re78)
m <- oal_match(fit, method = "nearest", caliper = 0.2)
