Pseudo-population Bootstrap Methods for Survey Data

Description

The function pseudopop.boot.stsrs applies one of the following pseudo-population bootstrap methods on complete (full response) survey data selected under either SRSWOR or STSRSWOR: Bickel and Freedman (1984), Chao and Lo (1985), Sitter (1992, CJS), Booth, Butler and Hall (1994) and Chao and Lo (1994).

Usage

pseudopop.boot.stsrs(
  data,
  population.size,
  R.pop,
  R.samp,
  parameter = "total",
  bootstrap.method = "Booth.Butler.Hall"
)

Arguments

data	A vector, matrix or data frame. If it is a matrix or data frame then the column of study variable has to be named study.variable. If the sampling design is STSRSWOR, a column identifying strata named stratum has to be included.
population.size	A vector of stratum population sizes
R.pop	The number of bootstrap replicates to create bootstrap pseudo-populations
R.samp	The number of bootstrap replicates to draw bootstrap samples from each bootstrap pseudo-population
parameter	One of the following population parameters can be applied: "total" (population total), "mean" (population mean), "quartile.25" (population 1st quartile), "quartile.50" or "median" (population median) or "quartile.75" (population 3rd quartile). If the parameter of interest is the population mean or total, the HT-estimator is applied. If the parameter of interest is a population quartile, the estimator in Sarndal, Swensson, and Wretman (1992, Chapter 5) is applied. The default is the population total.
bootstrap.method	One of the following bootstrap methods can be applied: "Bickel.Freedman" (Bickel and Freedman, 1984),"Chao.Lo.1985" (Chao and Lo, 1985), "Sitter.BWO" (Sitter, 1992), "Booth.Butler.Hall" (Booth, Butler and Hall, 1994) or "Chao.Lo.1994" (Chao and Lo, 1994). The default is "Booth.Butler.Hall".

Value

boot.statistic A vector of bootstrap statistics

boot.parameter A vector of bootstrap parameters computed on bootstrap pseudo-populations

boot.var The bootstrap variance estimator of the estimator of parameter of interest

boot.mean The average of the bootstrap estimator of the parameter of interest

boot.sample A list of size R.pop. Each list contains a list of results on each generated bootstrap pseudo-population. This includes three columns: bootstrap values, selected indices in each stratum, and a stratum identifier column.
