Statistics - Theory and Applications
INAR models, count time series, stochastic processes, thinning operators, random environments, regime-switching models, discrete-valued modeling, time series inference, applied statistics.
Stochastic modeling of integer-valued time series, with emphasis on regime-switching, and thinning-based frameworks.
• Construction and analysis of INAR and INAR-like models for count data
• Regime-switching and random environment processes
• Statistical inference for non-stationary time series
• Model-based clustering and state estimation
• Applications in reliability, demography, epidemiology, finance, and social systems
