Semi-parametric estimation of Autoregressive Conditional Duration (ACD) models


Method of Maximum Likelihood (ML) is used to estimate ACD model parameters. Estimating Function (EF) is a popular semi-parametric approach in time series modelling. This project develops the EF approach for ACD modelling.
