The function produces a graphical output of the ITP results: the plot of the functional data and the one of the adjusted pvalues.
The basis components selected as significant by the test at level alpha1
and alpha2
are highlighted in the plot of the corrected pvalues and in the one of functional data (in case the test is based on a local basis, such as Bsplines) by gray areas (light and dark gray, respectively).
