Extract the inverse-probability weights of an oal fit

Returns object$weights: the IPW weights at the fitted estimand implied by the clipped propensity score (ATE: \(A/e + (1-A)/(1-e)\); ATT: \(A + (1-A)\,e/(1-e)\)). For other estimands use WeightIt::get_w_from_ps(object$ps, object$treat, estimand = ...) or oal_weight().

Usage

# S3 method for class 'oal'
weights(object, ...)

Arguments

object

An oal object.

...

Ignored.

Value

The numeric vector object$weights, named by rownames(data).
