Despite their importance, likelihood-based inference with these models is challenging because a closed-form expression of the likelihood function is unavailable except in the simplest cases. This dissertation introduces three projects aimed at advancing likelihood-based inference for state space models.\r\n\r\nThe first project proposes a novel algorithm for maximum likelihood estimation of the parameters of Auto Regressive Moving Average (ARMA) models, which are formally a special case of linear Gaussian state space models. The proposed algorithm overcomes underrecognized optimization shortcomings of existing parameter estimation methods. The second project presents a likelihood-based analysis of the 2010-2019 cholera outbreak in Haiti. This work demonstrates the effectiveness of recently developed algorithms for performing inference on high-dimensional models. A key focus of this project is to assess the strengths and limitations of using state space models to inform public health policy decisions. The third project, which is the primary focus of my presentation, is a novel simulation-based algorithm called the Marginalized Panel Iterated Filter (MPIF). This algorithm is designed for maximum likelihood estimation of parameters from large collections of independent state space models. Theoretical support for this algorithm is provided through an analysis of iterating marginalized Bayes maps. New theoretical developments for the convergence of iterated filtering algorithms on this class of models are also derived.", "occurrence_notes":null, "guid":"135647-21877033@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/135647", "building_id":"1000167", "building_name":"West Hall", "campus_maps_id":"163", "room":"438", "location_name":"West Hall", "has_livestream":0, "cost":"", "tags":["Dissertation"], "website":"", "sponsors":[ { "group_name":"Department of Statistics Dissertation Defenses", "group_id":"4045", "website":"" } ], "image_url":"", "styled_images":{ "event_thumb":"", "event_large":"", "event_large_2x":"", "event_large_lightbox":"", "group_thumb":"", "group_thumb_square":"", "group_large":"", "group_large_lightbox":"", "event_large_crop":"", "event_list":"", "event_list_2x":"", "event_grid":"", "event_grid_2x":"", "event_feature_large":"", "event_feature_thumb":"" }, "occurrence_count":1, "first_occurrence":21877033 } , "135137-21876352": { "datetime_modified":"20250529T142017", "datetime_start":"20250529T150000", "datetime_end":"20250529T163000", "has_end_time":1, "date_start":"2025-05-29", "date_end":"2025-05-29", "time_start":"15:00:00", "time_end":"16:30:00", "time_zone":"America\/Detroit", "event_title":"OGPS Science Writing & Communication Workshop Series Spring 2025", "occurrence_title":"Writing Confidently: Strategies for Success and Productivity", "combined_title":"OGPS Science Writing & Communication Workshop Series Spring 2025: Writing Confidently: Strategies for Success and Productivity", "event_subtitle":"", "event_type":"Workshop \/ Seminar", "event_type_id":"21", "description":"OGPS Career & Professional Development - Science Writing & Communication\n\nThis series of workshops aims to equip you with practical skills and knowledge for writing science with confidence as part of your training (MS, PhD, or postdoc).

Due to strong Coulomb interaction, they provide an important platform for studying many-body complexes or quasi-particles such as excitons, trions, bi-excitons, and other possible new species. This talk will focus on our recent results of spectroscopic studies of the monolayer MoTe2, especially the existence of possible new species involving three and four electrons and holes. We will show that the common concept of a trion needs to be re-examined and there is a spectral splitting between a charged exciton and a genuei trion. In the case of four fermions, our combined theoretical and experimental results will be presented to show strong evidence for the existence of a new four-particle entity, a genuei four-body bound state called quadruplon which does not involve excitons and is different from the bi exciton. \r\n\r\nDr. Ning is a Chaired Professor and a College Dean at Shenzhen Tech University.
