Title: Direct Age Standardisation with Confidence Intervals
Version: 0.0.2
Description: Provides tools to compute directly age-standardised rates using the 2013 European Standard Population. Includes variance estimation and 95% confidence intervals for population health applications. Functions are flexible to handle any grouping variable and age bands, allowing reproducible and automated analyses.

Direct Age Standardisation with Confidence Intervals

Description

Computes directly age-standardised rates with 95% confidence intervals using the 2013 European Standard Population and Byar’s method.

Usage

direct_age_standardise(
  data,
  var,
  ageband,
  observed,
  population,
  multiplier = 1000
)

Arguments

data

Dataframe with observed values and population

var

One or more grouping variables (quoted or unquoted)

ageband

Column specifying age bands

observed

Column with observed counts

population

Column with denominator population

multiplier

Scale for rates (default = 1,000)

Value

A tibble with directly standardised rates and 95% confidence intervals

Examples

example_data <- data.frame(
  variable = c("A", "A", "B", "B"),
  ageband = c("0-4", "5-9", "0-4", "5-9"),
  observed = c(10, 20, 15, 25),
  population = c(1000, 1200, 1100, 1300)
)

direct_age_standardise(
  data = example_data,
  var = "variable",
  ageband = "ageband",
  observed = "observed",
  population = "population"
)

European Standard Population 2013 (abridged)

Description

A dataset containing abridged ESP 2013 standard population counts for use in age standardisation.

Usage

ref_population

Format

A data frame with 19 rows and 2 variables:

AgeBand

Age group (character, e.g. "0-4", "5-9")

StdPopulation

Standard population count for that age band
