SUMMARY:A General Identification Algorithm For Data Fusion Problems Under S
 ystematic Selection
DESCRIPTION:Speaker: Spandan Poddar (TIFR)\n\nAbstract: \nIdentification of
  causal effects can be hampered by confounding\, selection bias\, and othe
 r complications. Data fusion is one approach to addressing these difficult
 ies\, through the inclusion of auxiliary data on the population of interes
 t. Such data may measure a different set of variables\, or be obtained und
 er different experimental or observational conditions than the primary dat
 aset. In particular\, selection of experimental units into different datas
 ets may be systematic\; similar difficulties are encountered in missing da
 ta problems. However\, existing methods for combining datasets either do n
 ot consider this issue\, or assume simple selection mechanisms. In this pa
 per\, we propose a general approach\, based on graphical causal models\, f
 or causal inference from data on the same population that is obtained unde
 r different experimental conditions. Our framework allows both arbitrary u
 nobserved confounding\, and arbitrary selection processes into different e
 xperimental regimes in our data. We describe how systematic selection proc
 esses may be organized into a hierarchy similar to censoring processes in 
 missing data: selected completely at random\, selected at random\, and sel
 ected not at random. Finally\, we provide a novel general identification a
 lgorithm for interventional distributions in this setting.\nAuthors: Jaron
