Abstract:

This paper studies the minimum distance estimate for stochastic functional differential equations (McKean-Vlasov SDE). Under some assumptions for the drift coefficient, it obtains the consistency and the limit distribution on the estimators as the diffusion coefficient goes to zero. Further, it also discusses the asymptotic behavior of the coefficient estimators under the condition of the $ L^\gamma $ penalty function. A typical case is provided.

Key words: Wasserstein metric, Minimum distance estimation, Gronwall's inequality, Distribution measure
