prevcounts: Prevalence and Relative Standard Errors by Counts

Description

Prevalence and Relative Standard Errors by Counts

Usage

prevcounts(N, N_H, N_testR, N_R, DE_H = 1, DE_R = 1)

Arguments

N

Counts of total survey sample size(s) (vector/integer).

N_H

Number of HIV positive found in survey(s) (vector/integer).

N_testR

Number tested for recency in survey(s) (vector/integer).

N_R

Number of recent cases in survey(s) (vector/integer).

DE_H

Design effect of HIV prevalence test (vector/numeric), greater than or equal to 1. If multiple surveys are entered but only one design effect is specified, function assumes entered design effect is identical for both surveys.

DE_R

Design effect of recency test (vector/numeric), greater than or equal to 1. If multiple surveys are entered but only one design effect is specified, function assumes entered design effect is identical for both surveys.

Value

Prevalences and relative standard errors. Design effects are assumed negligible unless user specifies otherwise.

Examples

# NOT RUN {

prevcounts (N = c(5000,5000), N_H = c(1000,1000), N_testR = c(1000,1000),
N_R = c(100,70), DE_H = c(1,1.1), DE_R = c(1,1.1))
