Implementing Maximum Likelihood Estimation (MLE): Parameter Estimation and Confidence Intervals from Data

The second day of the Inference Track at the MIDSEA Summer School 2025, held on June 24, 2025, in the Yudhistira Room at the MICC, The Alana Yogyakarta Hotel and Convention Center, was a success. The session, titled “Implementing MLE,” discussed the challenges of applying Maximum Likelihood Estimation (MLE) to complex statistical models. One issue explored was the uncertainty in parameter estimation, especially when dealing with models that have many variables and parameters. In this session, participants learned how numerical and optimization methods can be used to find parameters that maximize the likelihood function, even though the models used often involve uncertainty and imperfect data. ...

Realistic Simulation of Infectious Disease Models: Duration of Disease Phases and Uncertainty

The second day of the Simulation Track at the MIDSEA Summer School 2025 on June 24, 2025, proceeded smoothly. Held in the Bima Room at the MICC Building, The Alana Yogyakarta Hotel and Convention Center, the session titled “Sojourn Times and Uncertainty” discussed the unrealistic nature of the standard infectious disease model (SIR), which consists of three compartments or phases: the susceptible phase (S), the infected phase (I), and the recovered phase (R). This is due to the fact that the population size in each phase is not an integer, and the deterministic model does not account for the duration of time an individual spends in a particular phase. ...
