MarronWand: Marron-Wand-like Specific Multivariate Normal Mixture 'norMmix' Objects

Description

Nicolas Trutmann constructed multivariate versions from most of the univariate (i.e., one-dimensional) "Marron-Wand" densities as defined in CRAN package nor1mix, see MarronWand (in that package).

Usage

## 2-dim examples:
MW21   # Gaussian
MW22   # Skewed
MW23   # Str Skew
MW24   # Kurtotic
MW25   # Outlier
MW26   # Bimodal
MW27   # Separated (bimodal)
MW28   # Asymmetric Bimodal
MW29   # Trimodal
MW210  # Claw
MW211  # Double Claw
MW212  # Asymmetric Claw
MW213  # Asymm. Double Claw
MW214  # Smooth   Comb
MW215  # Trimodal
## 3-dim :
MW31
MW32
MW33
MW34
## 5 - dim:
MW51    # Gaussian

Value

A normal mixture model. The first digit of the number in the variable name encodes the dimension of the mixture; the following digits merely enumerate models, with some correlation to the complexity of the model.
