Informing Clients of Negative Aspects of a Hot Topic (302795)*David R. Bristol, Statistical Consulting Services Inc
Keywords: Communication, Adaptive designs
Various statistical topics have become popular, often because clients are aware of the positive aspects of the techniques. The information regarding the negative aspects is overlooked, if provided. Adaptive designs, especially sample size re-estimation, have reached this level of popularity. Recently clients have insisted that the designs of their studies include sample size re-estimation. However, the procedures have inherent inefficiencies which need to be communicated to the client. Some of these inefficiencies are described here, with a simple communication process: inform the client with examples that are impactful and easy to understand, and provide alternatives.
