Department Head Jelena Kovačević on the Reproducibility Workshop Committee hosted by the NRC of the National Academies


February 24, 2015

Jelena Kovačević, Electrical and Computer Engineering Department Head and Schramm Professor, is a member of the organizing committee for the Workshop on the Statistical Challenges in Assessing and Fostering the Reproducibility of Scientific Results, hosted by the Committee on Applied and Theoretical Statistics of the National Research Council of the National Academies. The Workshop will be held February 26-27 in Washington, DC and will examine three issues from a statistical perspective: the extent of reproducibility, the causes of reproducibility failures, and potential remedies:

  • What are appropriate metrics and study designs that can be used to quantify reproducibility of scientific results?
    • Variability across studies is a well-known phenomenon and has given rise to the field of research synthesis and meta-analysis. How should this variability be assessed? What degree of variability would lead to concerns about lack of reproducibility?
  • How can the choice of statistical methods for study design and analysis affect the reproducibility of a scientific result?
    • How does routine statistical hypothesis testing with widely used thresholds for test significance affect the reproducibility of results? How do standard methods for study design and choice of sample size affect reproducibility?
  • Are there analytical and infrastructural approaches that can enhance reproducibility, within disciplines and overall?
    • Do we need new conceptual/theoretical frameworks for assessing the strength of evidence from a study? Do we need broad adoption of practices for making study protocols and study data available to the scientific community? How can this be achieved?
