# Conditional bias reduction can be dangerous: a key example from sequential analysis

## TL;DR

This paper demonstrates that applying conditional bias reduction in sequential analysis can lead to infinite mean absolute error, highlighting potential dangers of this approach.

## Contribution

It provides a critical example showing that conditional bias reduction may have unintended harmful effects in sequential analysis.

## Key findings

- Conditional bias reduction can cause infinite mean absolute error.
- The paper offers a key example illustrating this danger.
- Highlights the need for caution in bias reduction methods.

## Abstract

We present a key example from sequential analysis, which illustrates that conditional bias reduction can cause infinite mean absolute error.
