The construction of a warehouse using data from DuPont Pharmaceutical’s Clinical Pharmacokinetics Group with the SAS/Warehouse Administrator product is described herein. Data sources incorporated into the pharmacokinetic warehouse existed in multiple formats (Oracle, Excel, SAS data sets, etc) and were represented by numerous individual files, rather then few large files. In most cases, the da...

Continuing experimental work on SAS data set compression presented at NESUG in 2004, I designed another two-factor factorial experiment. My first factor compares the three kinds of data set compression offered by SAS on UNIX; the SAS DATA set OPTIONS COMPRESS=CHAR, COMPRESS=BINARY and SAS sequential format files created with the V9TAPE engine, three UNIX file compression algorithms; compress, g...

After years of using mainframe-based batch applications, though they were user-friendly, my users wanted something GUI, something that runs on their desktop, and something that interchanges with their MS-Windows applications. So, I set out to convert my batch application system to something my users wanted. Armed with the SAS System®, Base SAS, SAS/CONNECT®, SAS/AF®, SAS/FSP®, a TCP/IP connecti...

PURPOSE The purpose is to compare the molecular characteristics of serrated adenomas (SAs) with those of conventional adenomas (CADs) and hyperplastic polyps (HPs). EXPERIMENTAL DESIGN We evaluated the proliferative activity and molecular alterations in 47 SAs (25 pure-type and 22 mixed-type), 71 CADs, and 23 HPs. RESULTS The proliferative activity of SAs, as evaluated by Ki-67 expression, ...
