Abstract : We consider the Best Linear Predictor (BLP) of Functional Autoregressive Processes built with orthogonal
projection on linearly closed subspaces introduced by R.Fortet.
We show almost sure convergence and uniform convergence of the predictors. We then provide exponential bounds for the
predictors extending and improving previous results existing in the prediction of C[a,b] space and auto-reproducing kernel
space valued processes.
We illustrate the finite sample performance of the predictors by a simulation study and through real examples from
climatology comparing with others prediction methods existing in the literature.
This simulation study enlighten on the link between the convergence rates of predictors BLP and the presence of the first
eigenvalues of the covariance operator and sample size.
Keywords - Functional Autoregressive Processes, enclosed subspace, measurable linear transformations, orthogonal
projection, El Nino series.
