Graphical user interface for NEPSscaling available


The new version 3.0.0 of the R package NEPSscaling allows to perform independent estimation of Plausible Values (PV) using a graphical user interface. This interface provides additional tools for visualizing the estimated PV and the imputations of background data. Furthermore, the estimation of PV for grammar in Starting Cohort 2 as well as the introductory usage examples were updated. All available combinations of Starting Cohort, competence domain and assessment wave can be retrieved with the package’s function “currently_implemented()”. The R package and all other documents can be downloaded from the NEPS website.

Plausible Values can be used to describe the competencies of people at a group level. On the basis of the individual responses to the respective competence tests as well as additional background characteristics, the probability distribution of each person's competence is first determined and several values are randomly drawn from this. The analysis is then calculated individually for each Plausible Value and summarized into an overall result. This allows estimates of effects at the population level to be adjusted for measurement errors and is therefore particularly suitable for inferential statistical tests in correlation and mean value analyses. For further information on the estimation and handling of Plausible Values in the context of the National Educational Panel Study (NEPS) as well as instructions and an example of the use of the R-package “NEPSscaling” for generating your own plausible values, please refer to the NEPS Survey Paper No. 71 by Anna Scharl, Claus H. Carstensen and Timo Gnambs.
