- PROSSIMO SEMINARIO -

Data:  Venerdì 9 giugno 2017, ore 11.30

Guido Imbens (Stanford University, USA)  terrà il seguente seminario : 

Exact P-values for Network Interference <http://local.disia.unifi.it/abstract-seminari.php?#134>

We study the calculation of exact p-values for a large class of non-sharp null hypotheses about treatment effects in a setting with data from experiments involving members of a single connected network. The class includes null hypotheses that limit the effect of one unit's treatment status on another according to the distance between units; for example, the hypothesis might specify that the treatment status of immediate neighbors has no effect, or that units more than two edges away have no effect. We also consider hypotheses concerning the validity of sparsification of a network (for example based on the strength of ties) and hypotheses restricting heterogeneity in peer effects (so that, for example, only the number or fraction treated among neighboring units matters). Our general approach is to define an artificial experiment, such that the null hypothesis that was not sharp for the original experiment is sharp for the artificial experiment, and such that the randomization analysis for the artificial experiment is validated by the design of the original experiment. (with Susan Athey and Dean Eckles)

Referente: F. Mealli

Il seminario sara' tenuto presso l’aula 32 del DiSIA, Viale Morgagni n. 59 - 50134 Firenze.
