nSRS: Calculates the sample size for SRS

In cgu-dados/auditsampling: A auxiliary package to calculate some basic things in sampling. Most used para CGU auditors.

Description

This function calculates de sample size in a SRS design based on one of three possible arguments: σ^2, pq or CV. Provide just one of then.

Usage

nSRS(moe, alpha, CV = NULL, S2 = NULL, pq = NULL, N = Inf)

Arguments

moe	Margin of error.
alpha	1 - (confidence level).
CV	Variaton coefficient.
S2	σ^2, population variance.
pq	P(1 - P), population variance for proportions.
N	Population size.

Value

The value of n.

Examples

nSRS(moe=0.05,alpha=0.05,S2=6,N=1500)
nSRS(moe=0.05,alpha=0.05,CV=0.2,N=1500)
nSRS(moe=0.05,alpha=0.05,pq=0.25,N=1500)
