In this paper we consider the asymptotic properties of least squares estimators of the parameters of linear and nonlinear ARMAX models under data heterogeneity, where we allow the X-variables to be ...

Multivariate functional data are increasingly encountered in data analysis, whereas statistical models for such data are not well developed yet. Motivated by a case-study where one aims to quantify ...

"The findings provide a novel perspective on how neural representations can be altered with experience," says Huanqiu Zhang, a graduate student in Sharpee's lab. "The geometric principles ...
