Title: Computer Experiments with Binary Time Series and Applications to Cell Biology: Modeling, Estimation and Calibration
Author(s): C F Jeff Wu* and Ying Hung

Keywords: binary time series; calibration; computer experiments

Computer experiments have become ubiquitous in various applications from rocket injector designs to weather forecasting. In spite of the extensive research literature, computer experiments with binary time-series outputs have received scant attention. Motivated by the analysis of a class of cell adhesion experiments, we introduce a new emulator as well as a new calibration framework for binary time-series outputs. We provide their theoretical properties to ensure the estimation performance in an asymptotic setting. The application to the cell adhesion experiments illustrates that the proposed emulator and calibration framework can not only provide an efficient alternative for the computer simulation, but also reveal important insight on the underlying adhesion mechanism, which cannot be directly observed through existing methods.
