%description
Routines for model-based functional cluster analysis for functional data
with optional covariates. The idea is to cluster functional subjects
(often called functional objects) into homogenous groups by using spline
smoothers (for functional data) together with scalar covariates. The
spline coefficients and the covariates are modelled as a multivariate
Gaussian mixture model, where the number of mixtures corresponds to the
number of clusters. The parameters of the model are estimated by
maximizing the observed mixture likelihood via an EM algorithm (Arnqvist
and Sjöstedt de Luna, 2019) <arXiv:1904.10265>. The clustering method is
used to analyze annual lake sediment from lake Kassjön (Northern Sweden)
which cover more than 6400 years and can be seen as historical records of
weather and climate.
