This function produces a list of objects,
each of them contains the result of applying
a scalar response variable and multivariate functional covariates
evolved up to an intermediate domain point.
See Capezza et al. (2020) for additional details on real-time monitoring.
sof_pc_real_time( y, mfd_real_time_list, single_min_variance_explained = 0, tot_variance_explained = 0.9, selection = "PRESS", components = NULL, ncores = 1 )
A numeric vector containing the observations of the scalar response variable.
A list created using
get_mfd_list_real_time, denoting a list of functional data objects,
each evolving up to an intermediate domain point,
with observations of the multivariate functional covariates.
If you want parallelization, give the number of cores/threads to be used when creating objects separately for different instants.
A list of lists each produced by
corresponding to a given instant.
