Researchers have introduced a new statistical method called "confidence horizons" that allows for anytime-valid inference with a bounded time horizon. This approach aims to provide sharper statistical results by forgoing validity beyond a predetermined time limit, unlike traditional methods that assume infinite horizons. The paper details how these confidence horizons can be viewed as group sequential repeated confidence intervals and derives closed-form distribution functions for calculating asymptotic quantiles, simplifying calculations compared to standard group sequential methods. The proposed method is illustrated with an application in estimating treatment effects in adaptive randomized experiments. AI
