Sample size calculation

Description

Sample size calculation

Usage

sample_size(
  type,
  err_mean = 2,
  sd_mean = 10,
  err_prop = 0.1,
  p_prop = 0.5,
  conf_lev = 0.95,
  incidence = 1,
  response = 1,
  pop_correction = "no",
  pop_size = 1e+06
)

Arguments

type

Choose "mean" or "proportion"

err_mean

Acceptable Error for Mean

sd_mean

Standard deviation for Mean

err_prop

Acceptable Error for Proportion

p_prop

Initial proportion estimate for Proportion

conf_lev

Confidence level

incidence

Incidence rate (i.e., fraction of valid respondents)

response

Response rate

pop_correction

Apply correction for population size ("yes","no")

pop_size

Population size
