Abstract: The exploration of dynamic
systems governed by Ordinary Differential Equations (ODEs) holds great interest
in the field of statistics. Existing research mainly focuses on a single
function. This study generalizes the scope to analyze a collection of functions
observed at discretized times, with sampling frequencies varying from sparse to
dense designs. The range of ODE models studied caters to diverse dynamic
systems, and includes the complex non-linear and non-Lipschitz scenarios. We
introduce a new concept named Functional Moment Method, a novel approach for
parameter estimation within these ODE models and facilitating the recovery of
curves for the discretely observed functions. Our numerical analysis
underscores the methods applicability across various application fields,
including sociology, physics, and epidemiology.
