Metamorphic Robustness Testing: Exposing Hidden Defects In Citation Statistics And Journal Impact Factors, Zhi Q. Zhou, T.H. Tse, Matt Witheridge
Metamorphic Robustness Testing: Exposing Hidden Defects In Citation Statistics And Journal Impact Factors, Zhi Q. Zhou, T.H. Tse, Matt Witheridge
Faculty of Engineering and Information Sciences - Papers: Part B
We propose a robustness testing approach for software systems that process large amounts of data. Our method usesmetamorphic relations to check software output for erroneous input in the absence of a tangible test oracle. We use this technique to testtwo major citation database systems: Scopus and the Web of Science. We report a surprising finding that the inclusion of hyphensin paper titles impedes citation counts, and that this is a result of the lack of robustness of the citation database systems in handlinghyphenated paper titles. Our results are valid for the entire literature as well as for individual fields such …
Innovations Of The Assessment System In Introductory Statistics Subject, Norhayati Baharun, Anne Porter
Innovations Of The Assessment System In Introductory Statistics Subject, Norhayati Baharun, Anne Porter
Faculty of Engineering and Information Sciences - Papers: Part A
This paper presents the results of a study investigating the innovations in the assessment system implemented in an introductory statistics subject (STAT131) at the University of Wollongong (UOW). For several years, innovations have been introduced to STAT131 particularly in the assessment system. These included the approaches of assignments, summary and mid-session test in 2003; assignments, laboratory work and midsession test from 2004 to 2005; four tests and three make-up tests in 2006; six tests with three compulsory and two optional tests in 2007; four tests (the best of three test marks were chosen) and opportunity to re-sit the tests in …
A Web-Based Learning Support To Improve Students' Learning Of Statistics, Norhayati Baharun, Anne L. Porter
A Web-Based Learning Support To Improve Students' Learning Of Statistics, Norhayati Baharun, Anne L. Porter
Faculty of Engineering and Information Sciences - Papers: Part A
This study investigating the impact of a web-based learning supports particularly a Headstart program on student outcomes in statistics at the University of Wollongong. Unlike in 2010, a Headstart program was introduced to the undergraduate students enrolled in an introductory statistics subject in 2011. This program allowed students to access the first module of work which includes a set of five lecture notes, video clips, and the first assessment via the subject e-learning site approximately four weeks prior to the start of the formal session. For the assessment, the students were required to complete a draft and redraft the first …
The Berry-Esseen Bound For Studentized Statistics, Qiying Wang, Bing-Yi Jing, Lincheng Zhao
The Berry-Esseen Bound For Studentized Statistics, Qiying Wang, Bing-Yi Jing, Lincheng Zhao
Faculty of Engineering and Information Sciences - Papers: Part A
We derive Berry-Esseen bounds for a class of Studentized statistics. The results are applied to Studentized U-statistics, Studentized L-statistics and Studentized functions of the sample mean to give the Berry-Esseen bounds under conditions weaker than those obtained by alternative methods.
