simulateT {audit} R Documentation

## Simulating the Total Number of Accounts in Error

### Description

Considered a stratified finite population of accounts where each account is classified as either acceptable or in error. Based on a stratified random sample of accounts an auditor is required to give an upper 95 the population that are in error. Given the sample this uses the posterior distribution from a simple hierarchical Bayes model to simulate possible values for T. The 0.95 quantile for this posterior will be an approximate 95 populations.

### Usage

```  simulateT(smp,n,N,grd,R)
```

### Arguments

 `smp` numeric vector of the number of accounts in error in each strata in the sample `n` numeric vector of the number of accounts sampled in each strata in the population `N` numeric vector of the total number of accounts in each strata in the population `grd` numeric vector of values usually taken to be seq(0.0001,0.1499,length = 11) `R` an integer which is the number of simulated values of T returned

### Value

A vector of length R containing simulated values of T

```grd <- seq(0.0001,0.15,length = 11)
smp <- c(2,1,0)
n <- c(75,50,25)
N <- c(5000,3000,2000)
as.numeric(quantile(simulateT(smp,n,N,grd,40000),0.95))
