Extracts the inverse probability weights — weights.nonprob • nonprobsvy

A generic function weights that returns inverse probability weights (if present)

Usage

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

Arguments

object: a nonprob class object
...: other arguments passed to methods (currently not supported)

Value

A vector of weights or a NULL extracted from the nonprob object i.e. element "ipw_weights"

Examples


data(admin)
data(jvs)

jvs_svy <- svydesign(ids = ~ 1,  weights = ~ weight,
strata = ~ size + nace + region, data = jvs)

ipw_est1 <- nonprob(selection = ~ region + private + nace + size,
target = ~ single_shift,
svydesign = jvs_svy,
data = admin, method_selection = "logit", se = FALSE
)

summary(weights(ipw_est1))
