Bootstrap sampling function for use with pre-designated strata proportions

Description

Function for bootstrap summary statistics using data and pre-designated strata proportions.

Usage

bootstrapSRS(
        summary_variable,
        strata_variable,
        population_strata_proportions,
        sample_size=NULL,
        bootstrap_iterations=100,
        summary_statistic="mean",
        return_bootstrap_distribution=FALSE)

Arguments

summary_variable
strata_variable
population_strata_proportions
sample_size
bootstrap_iterations
summary_statistic
return_bootstrap_distribution

Details

Function calculates a summary statistic of existing data (e.g., mean) by re-sampling based upon designated strata proportions

Value

Function returns either a list (default) containing the summary statistic (e.g., mean) and standard deviation (i.e., standard error) for the bootstrap sample of that statistic or funtion returns a vector containing the bootstrap replication values.
