Sensitivity analysis of statistical models is aimed here at finding influential observations that affect the model considered.

In this article, using the so-called influence curve, a number of techniques are presented for assessing the sensitivity to a single or a group of data in regression analysis, time series, and spatiotemporal models.


  • influence curves;
  • influence functions;
  • robustness;
  • Cook's distance;
  • sensitivity analysis in state space models;
  • sensitivity analysis in space-time models;
  • sensitivity analysis in time series
