Returns confidence intervals for estimated mean — confint.nonprob • nonprobsvy

A generic function that returns the confidence interval for the estimated mean. If standard errors have not been estimated, the function updates the nonprob object to obtain standard errors.

Usage

# S3 method for class 'nonprob'
confint(object, parm, level = 0.95, ...)

Arguments

object: object of nonprob class.
parm: names of parameters for which confidence intervals are to be computed, if missing all parameters will be considered.
level: confidence level for intervals.
...: additional arguments

Value

returns a data.frame with confidence intervals for the target variables

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
)

confint(ipw_est1)
#> Calculating standard errors...
#> Error in eval(call, parent.frame()): object 'jvs_svy' not found
