From Wikipedia, the free encyclopedia

MaryAnn H. Hill is a retired American statistical software developer who contributed to statistics packages including BMDP, SYSTAT, and SPSS. She also published fundamental research on robust statistics,[1] as well as contributing statistical analyses to several medical research publications.

Career[edit]

In the 1970s, Hill worked for the University of California, Los Angeles (UCLA) as a developer of the BMDP (Biomedical Data Processing) package, including developing robust regression and ridge regression methods for BMDP.[2] She was later also credited with writing most of the documentation of the BMDP system.[3]

In the 1980s, she was listed as a senior statistician in the UCLA biomathematics program,[4] also affiliated with the VA Medical Center in Los Angeles,[1] and later in the UCLA Department of Psychiatry and as an employee of BMDP Statistical Software, Inc.[5] By the early 1990s, she was working in the department of statistics at the University of Michigan and at Systat Software Inc.,[6] working on the SYSTAT statistics package. SYSTAT was sold in 1995 to SPSS,[7] and in 1997 she authored a manual on missing data for SPSS, Inc.[8] She was also listed as a senior statistician at NORC at the University of Chicago in 1997.[9]

Recognition[edit]

Hill was named as a Fellow of the American Statistical Association in 1995.[10]

Personal life[edit]

Hill is the mother of biology professor Karlyn Mueller-Hill, who writes in her 1999 doctoral thesis that Hill's "idea of child day care was to bring [Karlyn] to her graduate classes in statistics".[11]
