Abstract
We saw in the last chapter that functions are built up from basis systems \(\phi_1 (t),..., \phi_K (t) \) by defining the linear combination
That chapter described how to build a basis system. Now we take the next step, defining a functional data object by combining a set of coefficients c k (and other useful information) with a previously specified basis system. Once we have selected a basis, we have only to supply coefficients in order to define an object of the functional data class (with class name fd).
