pg: Bias-reduced estimator

Description Usage Arguments Details Value Author(s) References See Also Examples

Description

Calculates the bias-reduced estimator of the true response rate as proposed by Guo and Liu (2005).

Usage

1
pg(s, n1, r1, n)

Arguments

s

Total number of successes.

n1

Stage 1 sample size.

r1

Stage 1 critical value (trial is stopped at stage 1 if the number of successes is at most r1).

n

Total sample size.

Details

It uses bias subtraction, with bias calculated by sbias and response rate estimated by pm.

Value

Estimate of the response rate.
