Grab it Explore the fundamentals of model fitting in this comprehensive lecture by Dr. James Nightingale from Centrum Fizyki Teoretycznej PAN. Delve into the application of model fitting techniques using an observational dataset centered on gravitational lensing, and learn how to extend these concepts to multiple observation datasets. Compare the traditional approach of fitting models to individual observations and combining results with the innovative graphical modeling technique that allows for fitting entire datasets simultaneously. Discover the advantages of graphical modeling and get introduced to PyAutoFit, a Python-based probabilistic programming language designed to streamline the model fitting process. This 1 hour and 29 minutes long video provides valuable insights for researchers and students interested in advanced data analysis techniques in astrophysics and related fields.
