ARD survey categorical CIs — ard_categorical

Confidence intervals for categorical variables calculated via survey::svyciprop().

Usage

# S3 method for survey.design
ard_categorical_ci(
  data,
  variables,
  by = NULL,
  method = c("logit", "likelihood", "asin", "beta", "mean", "xlogit"),
  conf.level = 0.95,
  value = list(where(is_binary) ~ 1L, where(is.logical) ~ TRUE),
  df = survey::degf(data),
  ...
)

Arguments

data: (survey.design)
a design object often created with survey::svydesign().
variables: (tidy-select)
columns to include in summaries.
by: (tidy-select)
results are calculated for all combinations of the columns specified, including unobserved combinations and unobserved factor levels.
method: (string)
Method passed to survey::svyciprop(method)
conf.level: (numeric)
a scalar in (0, 1) indicating the confidence level. Default is 0.95
value: (formula-list-selector)
function will calculate the CIs for all levels of the variables specified. Use this argument to instead request only a single level by summarized. Default is list(where(is_binary) ~ 1L, where(is.logical) ~ TRUE), where columns coded as 0/1 and TRUE/FALSE will summarize the 1 and TRUE levels.
df: (numeric)
denominator degrees of freedom, passed to survey::svyciprop(df). Default is survey::degf(data).
...: arguments passed to survey::svyciprop()
