sample_size: Sample size calculation

Description

Sample size calculation

Usage

sample_size(ss_type = "mean", ss_mean_err = 2, ss_mean_s = 10, ss_prop_err = 0.1, ss_prop_p = 0.5, ss_z = 1.96, ss_incidence = 1, ss_response = 1, ss_pop_correction = "no", ss_pop_size = 1000000)

Arguments

ss_type

Choose "mean" or "proportion"

ss_mean_err

Acceptable Error for Mean

ss_mean_s

Standard deviation for Mean

ss_prop_err

Acceptable Error for Proportion

ss_prop_p

Initial proportion estimate for Proportion

ss_z

Z-value

ss_incidence

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

ss_response

Response rate

ss_pop_correction

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

ss_pop_size

Population size

Value

A list of variables defined in sample_size as an object of class sample_size
