Title: The Impact of Rater Reliability on Statistical Inferences in Ordinal Ratings
Author(s): Paul Zhang*+
Companies: Pfizer Inc.
Address: 201 Tabor Rd., Morris Plains, NJ, 07950,
Keywords: rater reliability ; statistical power
Abstract:

Rater reliability of ordinal ratings cause concerns as to the validity and efficiency of statistical inferences on the mean ratings. We discuss the approaches to assess the rater reliability and its impact on the statistical inferences on the group mean ratings. The criterion for reducing these impacts in clinical trials using ordinal ratings are proposed.
