Diagnostic checking in FARIMA models with uncorrelated but non-independent error terms
Yacouba Boubacar Maïnassara, Youssef Esstafa, Bruno Saussereau
This work considers the problem of modified portmanteau tests for testing the adequacy of FARIMA models under the assumption that the errors are uncorrelated but not necessarily in…

Estimating FARIMA models with uncorrelated but non-independent error terms
Yacouba Boubacar Maïnassara, Youssef Esstafa, Bruno Saussereau
In this paper we derive the asymptotic properties of the least squares estimator (LSE) of fractionally integrated autoregressive moving-average (FARIMA) models under the assumption…
