CMS Hospital Compare Star Rating SAS Pack Replica

---

Introduction

The initial goal is to reimplement the SAS-Pack for the CMS Hospital Compare Overall Star Rating as posted on https://www.qualitynet.org. During the reimplementation, two major issues have been found:

• CMS's SAS Pack, which implements the k-means clustering with ONE iteratrion, failed to converge. This leads to ~ 1/4 hospitals receiving an incorrect star rating.

• CMS's Latent Variable Model (LVM), which uses a Gaussian quadrature approximation with 30 qpoints, failed to approach the integral of the objective function. This also leads to hundreds of hospitals receiving an incorrect star rating.
