This function selects number of principal components based on the total variation explained (TVE). The functional data is projected onto a smaller number of principal curves via functional Principal Component Analysis (fPCA). This function picks the dimension of the projection space based on the desired total variation explained.

Total Variation Explained. It must be in [0,1]. |
This function is used to determine the dimension of the space that the functional data is projected onto based on the variation. One of the common treatments of the functional data is to transform it to multivariate objects using so called score vectors and utilize the multivariate techniques. This function will enable users to pick the dimension of the score vectors.
