In this report, we propose a robust mixture of regression based on t-distribution by extending the mixture of t-distributions proposed by Peel and McLachlan (2000) to the regression setting. This new mixture of regression model is robust to outliers in y direction but not robust to the outliers with high leverage points. In order to combat this, we also propose a modified version of the propose...

Approved for public release; distribution is unlimited. ACKNOWLEDGMENTS These studies were conducted with the assistance and cooperation of the Fifth Marine Regiment, Camp Pendleton, CA. We would like to thank Colonel Brooks, Commanding Officer of Fifth Marines, and Major Turner (his S-3), for their unselfish dedication of time and effort in facilitating access to the officers and staff noncomm...

homogenous charge compression ignition (hcci) engines hold promise of high fuel efficiency and low emission levels for future green vehicles. but in contrast to gasoline and diesel engines, hcci engines suffer from lack of having direct means to initiate combustion. a combustion timing controller with robust tracking performance is the key requirement to leverage hcci application in production ...

We consider a model in which banking is characterized by asset substitution moral hazard and managerial under-provision of effort in loan monitoring. The privately-optimal bank leverage efficiently balances the benefit of debt in providing the discipline to ensure that the bank monitors its loans against the benefit of equity in attenuating asset-substitution moral hazard. However, when correla...

Since the fiduciary duty of bank management is to maximize bank value and not social welfare, we analytically solve for the liability structure that maximizes the value of a bank leveraged by deposits and subordinated debt. Our analysis offers a perspective on privately-rational bank capital structure and its interaction with regulatory environment. Absent deposit insurance and regulatory closu...

We consider firm financing when the firm quality is private information of the manager and, given its inherent quality, the project viability depends on the manager exerting unobservable effort. We show that capital structure matters even though managerial contracts are optimally designed. Good firms would like to issue more debt to avoid selling underpricing equity. However, the interaction be...

Information opacity leads to information asymmetry. In this situation, in providing their own financial needs, firms face limitations and inevitably provide their financial needs from the debt market by signalling private information to it. In addition, information opacity affects the leverage adjustment speed. This research investigates the effect of information opacity on deviation from targe...
