Extract standard errors from a survey result object — SE.survey

Returns a named numeric vector of standard errors from a survey_result object. Values are sqrt(diag(vcov(object))), ensuring consistency between SE() and vcov().

Usage

# S3 method for class 'survey_result'
SE(object, ...)

Arguments

object: A survey_result object from any supported get_*() function.
...: Unused.

Value

A named numeric vector. Names are identical to names(coef(object)). NA entries propagate from missing se column or NA in se.

Note

vcov.survey_result() emits surveycore_warning_vcov_diagonal_only when p > 1. This warning is suppressed inside SE.survey_result() because the off-diagonal structure is irrelevant when only standard errors are requested. Call vcov(result) directly to observe this warning.

Examples

d <- as_survey(
  nhanes_2017,
  ids = sdmvpsu,
  weights = wtint2yr,
  strata = sdmvstra,
  nest = TRUE
)
result <- get_means(d, ridageyr, variance = "se")
SE(result)
#>  ridageyr 
#> 0.5244057
