内容简介：Nonlinear
expectation, including sublinear expectation as its special case, is a new and
original framework of probability theory and has potential applications in some
scientific fields, especially in finance risk measure and econometrics. Under
the nonlinear expectation framework, however, the related statistical models
and statistical inferences have not yet been well established. The goal of this
paper is to construct the sublinear expectation regression and investigate its
statistical inference. First, a sublinear expectation linear regression is
defined and its identifiability is given. Then, based on the representation
theorem of sublinear expectation and the newly defined model, several parameter
estimations and model predictions are suggested, the asymptotic normality of
estimations and the mini-max property of predictions are obtained. Furthermore,
new methods are developed to realize variable selection for high-dimensional
model. Finally, simulation studies and a real financial example are carried out
to illustrate the new models and methodologies.
All notions and methodologies developed are essentially different from
classical ones and can be thought of as a foundation for general nonlinear
expectation statistics.
