data	(data.frame/survey.design) a data frame or object of class 'survey.design' (typically created with survey::svydesign()).
by	(tidy-select) column name to compare by.
variables	(tidy-select) column names to be compared. Independent tests will be computed for each variable.
std.error	(scalar logical) Logical indicator for computing standard errors using smd::compute_smd_var(). Default is TRUE.
conf.level	(scalar numeric) confidence level for confidence interval. Default is 0.95.
...	arguments passed to smd::smd()
