coarsen_index

Reduce the resolution of a numeric vector by specifying the number of
<code>significant_digits</code> to which the numbers should be rounded. 
Internal function used to coarsen the index vector before estimating the
two-step GFPCA with <code>gfpca_twoStep</code>.

A method for performing joint registration and functional principal
component analysis for curves (functional data) that are generated from exponential family distributions. This
mainly implements the algorithms described in 'Wrobel et al. (2019)' <doi:10.1111/biom.12963> and further adapts them to potentially
incomplete curves where (some) curves are not observed from the beginning and/or until the end of the common domain. Curve registration
can be used to better understand patterns in functional data by separating curves into phase and amplitude variability.
This software handles both binary and continuous functional data, and is
especially applicable in accelerometry and wearable technology.
