We extend the knockoffs method for selecting predictors to clustered data (cross-sectional or repeated measures). In the setting of clustered data, variable selection is complex be…
Variable selection via knockoffs in missing data settings with categorical predictors
Silvia Bacci, Emanuela Dreassi, Leonardo Grilli +1
Large-scale assessment data typically include numerous categorical variables, often affected by missing values. Motivated by the challenges arising in this framework, we extend the…
The effects of citation-based research evaluation schemes on self-citation behavior
Giovanni Abramo, Ciriaco Andrea D'Angelo, Leonardo Grilli
We investigate the changes in the self-citation behavior of Italian professors following the introduction of a citation-based incentive scheme, for national accreditation to academ…
Conditioning on the pre-test versus gain score modeling: revisiting the controversy in a multilevel setting
Bruno Arpino, Silvia Bacci, Leonardo Grilli +2
We consider estimating the effect of a treatment on the progress of subjects tested both before and after treatment assignment. A vast literature compares the competing approaches…
Multiple imputation and selection of ordinal level 2 predictors in multilevel models. An analysis of the relationship between student ratings and teacher beliefs and practices
Leonardo Grilli, Maria Francesca Marino, Omar Paccagnella +1
The paper is motivated by the analysis of the relationship between ratings and teacher practices and beliefs, which are measured via a set of binary and ordinal items collected by…
Funnel plots for visualizing uncertainty in the research performance of institutions
Giovanni Abramo, Ciriaco Andrea D'Angelo, Leonardo Grilli
Research performance values are not certain. Performance indexes should therefore be accompanied by uncertainty measures, to establish whether the performance of a unit is truly ou…
