Real Time Indicators During the COVID-19 Pandemic Individual Predictors & Selection


  • George Kapetanios
  • Fotis Papailias


This technical report aims to present a generalised framework for assessing the predictive content of ONS real time indicators in both dimensions: (i) individual predictors (i.e. variable-by-variable), and (ii) using machine learning techniques to build variable selection models. The evaluation is done on a nowcasting basis (h = 0). Simple correlation and predictive power scores are included as well as best subset selection, penalised regressions, random forests and principal components.
