Check the variable balance between the probability and non-probability samples

Description

Function compares totals for auxiliary variables specified in the x argument for an object that contains either IPW or DR estimator.

Usage

check_balance(x, object, dig)

Arguments

x

formula specifying variables to check

object

object of nonprob class

dig

number of digits for rounding (default = 2)

Value

A list containing totals for non-probability and probability samples and their differences

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"
)

ipw_est2 <- nonprob(
selection = ~ region + private + nace + size,
target = ~ single_shift,
svydesign = jvs_svy,
data = admin, method_selection = "logit",
control_selection = control_sel(est_method = "gee", gee_h_fun = 1))

## check the balance for the standard IPW
check_balance(~size, ipw_est1)

## check the balance for the calibrated IPW
check_balance(~size, ipw_est2)
