Calculate a pooled standard error for a proportion or ratio

Usage

se_proportion_ratio(
  estimate_numerator,
  estimate_denominator,
  moe_numerator = NULL,
  moe_denominator = NULL,
  se_numerator = NULL,
  se_denominator = NULL,
  type = "proportion"
)

Arguments

estimate_numerator: The estimate of the numerator
estimate_denominator: The estimate of the denominator
moe_numerator: The margin of error of the numerator
moe_denominator: The margin of error of the denominator
se_numerator: The standard error of the numerator
se_denominator: The standard error of the denominator
type: The type of estimate being calculated, either "proportion" or "ratio"

Value

A pooled 90% standard error

Details

For an estimate derived using division–whether the resulting estimate is a proportion or a ratio–calculate the pooled standard error. While there are convenience parameters that support both SEs and MOEs for the numerator and denominator, only one of these–either SEs or MOEs–can be supplied–the other must be left NULL.
