In carrollrm/survsamp: Estimation and Sample Size Determination for Elementary Survey Sampling Methods

Description

This function allows you to make estimation or sample size determinations for the ratio wtih surveys using simple random sampling.

Usage

survsamp.ratio(x = NULL, y = NULL, B = NULL, N = NULL, mux = NULL,
  taux = NULL, sig2 = NULL, sample.size.det = FALSE, estimate = "ratio",
  alpha = 0.05)

Arguments

x	The independent data vector to be used for estimation.
y	The dependent data vector to be used for estimation.
B	The desired bound on the estimation. Required for sample size determination.
N	The population size. Required for sample size determination.
mux	The population mean of x.
taux	The population total of x. This must be supplied if N is NULL.
sig2	The population variance.
sample.size.det	Logical statement indicating if the action should be sample size determination. If false, estimation occurs.
estimate	Indicate the desired statistic to be estimated. Options include: ratio, mean, and total. This is only needed for sample size determination as all three are reported in estimation.
alpha	Significance level.

Examples

x=rnorm(50,5,1)
survsamp.ratio(x=x,y=x+rnorm(50),
estimate="ratio",mux=5,N=100)
