improve readability of the code.
add some useful comments.
speedup MCD/ACD/HPC method (GH #2, @Neutron3529).
fix the warning on order() suggested by Kurt Hornik.
remove lattice from Imports.
fix a bug on model order (GH #1).
speedup HPC method (GH #2, @Neutron3529).
optim.method was missing to call function
optimizeJmcm(), and now it is set to 'default'.
add the JSS paper as vignette in package jmcm.
optim.method in function
optim.method is 'default' so that the BFGS algorithm
we implemented internally is used; alternatively, we can set
optim.method as 'BFGS' so that
vmmin() (the underlying C
function used in
stats::optim() for BFGS algorithm) will be
called through R package roptim.
JmcmBase is implemented as the base class for class
HPC to reduce code duplication.
JmcmFit is used for fitting of the three
Cholesky-based joint mean-covariance models (i.e., MCD, ACD and HPC).
