An Integrated Impact Indicator (I3): A New Definition of "Impact" with Policy Relevance [article]

Caroline S. Wagner, Loet Leydesdorff
2012 arXiv   pre-print
I3 has the added advantage of enabling and quantifying classifications such as the six percentile rank classes used by the National Science Board's Science & Engineering Indicators.  ...  Allocation of research funding, as well as promotion and tenure decisions, are increasingly made using indicators and impact factors drawn from citations to published work.  ...  The Annals of the New York Academy of Sciences follows at the fourth position in terms of I3, but if the six percentile ranks of the NSB are used, Annals no longer scores significantly above expectation  ...

A Comparison of Student Growth Percentile and Value-Added Models of Teacher Performance

Cassandra Guarino, Mark Reckase, Brian Stacy, Jeffrey Wooldridge
2015 Statistics and Public Policy  
Using simulated data, we examine how well the estimators can rank teachers and avoid misclassification errors under a variety of assignment scenarios of teachers to students.  ...  We find that growth percentile measures perform worse than valueadded measures that control for prior year student test scores and control for teacher fixed effects when assignment of students to teachers  ...  Description of the Models Both growth percentile and value-added approaches can take various forms.  ...

An evaluation of percentile measures of citation impact, and a proposal for making them better

Lutz Bornmann, Richard Williams
2020 Scientometrics  
Percentile Ranks (PRs) often play an important role in evaluating the impact of researchers, institutions, and similar lines of study.  ...  We offer a series of guidelines and procedures that, we argue, address these problems and others and provide a superior means to make the use of percentile methods more accurate and informative.  ...  The bibliometric data used in this paper are from an in-house database developed and maintained by the Max Planck Digital Library (MPDL, Munich) and derived from the Science Citation Index Expanded (SCI-E  ...

The Gains From Vertical Scaling

Derek C. Briggs, Ben Domingue
2013 Journal of educational and behavioral statistics  
A pragmatic approach is also presented to assess the departure of a given vertical scale from a scale with ideal equal-interval properties.  ...  Empirical data are used to compare school-level gain scores computed as a function of different vertical scales transformed to represent increasing, decreasing, and constant trends in score variability  ...  The basic idea is to compare competing scales with respect to departures from a percentile gain ratio of 1.  ...

LowCon: A design-based subsampling approach in a misspecified linear modeL [article]

Cheng Meng, Rui Xie, Abhyuday Mandal, Xinlian Zhang, Wenxuan Zhong, Ping Ma
2020 arXiv   pre-print
Both the simulated and real-data analyses demonstrate the proposed estimator is more robust than several subsample least squares estimators obtained by state-of-the-art subsampling methods.  ...  Thus, it is ideal to select a subsample of predictor observations, measure the corresponding responses, and then fit the supervised learning model on the subsample of the predictors and responses.  ...  Acknowledgment The authors thank the associate editor and two anonymous reviewers for provided helpful comments  ...
