Changes in version 0.2.5 (2025-10-13) USER-VISIBLE CHANGES o improve readability of the code. o add some useful comments. o speedup MCD/ACD/HPC method by paralleling code of objective function / gradient computation using OpenMP. Changes in version 0.2.4 (2021-01-12) USER-VISIBLE CHANGES o improve readability of the code. o add some useful comments. o speedup MCD/ACD/HPC method (GH #2, @Neutron3529). Changes in version 0.2.3 (2021-01-06) BUG FIXES o fix the warning on order() suggested by Kurt Hornik. o remove lattice from Imports. o fix a bug on model order (GH #1). USER-VISIBLE CHANGES o speedup HPC method (GH #2, @Neutron3529). Changes in version 0.2.2 (2020-07-28) BUG FIXES o fix function bootcurve(): argument optim.method was missing to call function optimizeJmcm(), and now it is set to 'default'. Changes in version 0.2.1 (2018-11-10) USER-VISIBLE CHANGES o add the JSS paper as vignette in package jmcm. Changes in version 0.2.0 (2018-11-04) USER-VISIBLE CHANGES o add option optim.method in function jmcm(): by default, 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. NEW FEATURES o class JmcmBase is implemented as the base class for class MCD, ACD and HPC to reduce code duplication. o class JmcmFit is used for fitting of the three Cholesky-based joint mean-covariance models (i.e., MCD, ACD and HPC).
