estimate_LC_pdfs
estimates the PLC and FLC
distributions for each state k = 1, …, K. It
iteratively applies estimate_LC.pdf.state
.
estimate_LC.pdf.state
estimates the PLC and
FLC distributions using weighted maximum likelihood
(cov.wt
) and nonparametric kernel
density estimation (wKDE
) for one (!)
state.

LCs 
matrix of PLCs/FLCs. This matrix has N rows and n_p or n_f columns (depending on the PLC/FLC dimensionality) 
weight.matrix 
N \times K weight matrix 
states 
vector of length N with entry i being the label k = 1, …, K of PLC i 
method 
type of estimation: either a (multivariate)
Normal distribution ( 
eval.LCs 
on what LCs should the estimate be
evaluated? If 
state 
integer; which stateconditional density should be estimated 
weights 
weights of the samples. Either a i) length
N vector with the weights for each observation; ii)
N \times K matrix, where the 
estimate_LC_pdfs
returns an N \times
K matrix.
estimate_LC.pdf.state
returns a vector of
length N with the stateconditional density
evaluated at eval.LCs
.
