<Piotr Kokoszka> studies <functional data analysis>, <time series> and spatial statistical methods. His Colorado State University homepage describes inference for observations that can themselves be curves.https://www.stat.colostate.edu/~piotr/[Author research statement]{ref}
With <Lajos Horváth> and <Ron Reeder>, he developed <estimation> and <statistical hypothesis testing> for mean curves under temporal dependence. Averaging many curves requires a covariance accounting for correlation between successive observations; treating the curves as independent can misstate uncertainty.<Estimation of the Mean of Functional Time Series and a Two-Sample Problem by Lajos Horváth and others>[Sections 2–3, asymptotic covariance and two-sample procedure]{ref}
