To apply these methods with large-scale data sets\, a major challenge is to find valid instruments from a possibl y large candidate set. In practice\, most of the candidate instruments are often not relevant for studying a particular exposure of interest. Moreov er\, not all relevant candidate instruments are valid as they may directly influence the outcome of interest. In this work\, we propose a data-drive n method for causal inference with many candidate instruments that address es these two challenges simultaneously. A key component of our proposal in volves using pseudo variables\, known to be irrelevant\, to remove variabl es from the original set that exhibit spurious correlations with the expos ure. Synthetic data analyses show that the proposed method performs favour ably compared to existing methods. We apply our method to a Mendelian rand omization study estimating the effect of obesity on health-related quality of life.\n\n📍 PLACE /  LIEU \n Hybride - Concordia\, Salle / Room LB921-4 \n\n \n\n\n \n \n \n Lien ZOOM Link\n \n \n \n\n DTSTART:20260327T193000Z DTEND:20260327T203000Z SUMMARY:Dehan Kong (University of Toronto) URL:/channels/channels/event/dehan-kong-university-tor onto-372080 END:VEVENT END:VCALENDAR
