In sampler: Sample Design, Drawing & Data Analysis Using Data Frames

Description

Draws stratifed sample without replacement using proportional allocation

Usage

ssamp(df, n, strata, over = 1)

Arguments

df	object containing full sampling data frame (e.g. data)
n	sample size (integer) or object containing sample size
strata	variable in sampling data frame by which to stratify (e.g. region)
over	(optional) desired oversampling proportion (defaults to 0; takes value between 0 and 1 as input)

Value

Returns stratified sample without replacement

Examples

ssamp(df=albania, n=360, strata=qarku, over=0.1)

size <- rsampcalc(nrow(albania), 3, 95, 0.5)
stratifiedsample <- ssamp(albania, size, qarku)
