KM.calc.sample {elec}

Calculate sample size for KM-audit.

Description

Calculate the size of a sample needed to certify a correct election if a KM audit is planned.

Usage

KM.calc.sample(Z, beta = 0.75, taint = 0, bound = c("e.plus", "WPM", "passed"))

Arguments

Z

elec.data object

beta

Desired level of confidence. This is 1-risk, where risk is the maximum chance of not going to a full recount if the results are wrong. Note that in Stark's papers, the value of interest is typically risk, denoted $alpha$.

taint

Assumed taint. Taint is assumed to be the taint for all batches (very conservative). If taint=0 then we produce a good baseline.

bound

Type of bound on the maximum error one could find in a batch.

Value

A audit.plan.KM object.

Author(s)

Based on the KM audit by Stark.
