“…However, forming valid tests of various hypotheses about the functional regression parameters, with the control of the error rate, is not straightforward. One solution adopted in the literature is to develop global tests for the parameters of the model (Abramovich & Angelini, 2006;Antoniadis & Sapatinas, 2007;Cardot et al, 2007;Cuesta-Albertos & Febrero-Bande, 2010;Cuevas, Febrero, & Fraiman, 2004;Kayano, Matsui, Yamaguchi, Imoto, & Miyano, 2015;Schott, 2007;Staicu, Li, Crainiceanu, & Ruppert, 2014;Zhang & Liang, 2014).
