RNGMIX-class {rebmix}R Documentation

Class "RNGMIX"

Description

Object of class RNGMIX.

Objects from the Class

Objects can be created by calls of the form new("RNGMIX", ...). Accessor methods for the slots are a.Dataset.name(x = NULL), a.rseed(x = NULL), a.n(x = NULL), a.Theta(x = NULL), a.Dataset(x = NULL, pos = 0), a.Zt(x = NULL), a.w(x = NULL), a.Variables(x = NULL), a.ymin(x = NULL) and a.ymax(x = NULL), where x and pos stand for an object of class RNGMIX and a desired slot item, respectively.

Slots

Dataset.name:

a character vector containing list names of data frames of size n×dn \times d that d-dimensional datasets are written in.

rseed:

set the random seed to any negative integer value to initialize the sequence. The first file in Dataset.name corresponds to it. For each next file the random seed is decremented rseed=rseed1r_{\mathrm{seed}} = r_{\mathrm{seed}} - 1. The default value is -1.

n:

a vector containing numbers of observations in classes nln_{l}, where number of observations n=l=1cnln = \sum_{l = 1}^{c} n_{l}.

Theta:

a list containing cc parametric family types pdfl. One of "normal", "lognormal", "Weibull", "gamma", "Gumbel", "binomial", "Poisson", "Dirac", "uniform" or circular "vonMises" defined for 0yi2π0 \leq y_{i} \leq 2 \pi. Component parameters theta1.l follow the parametric family types. One of μil\mu_{il} for normal, lognormal, Gumbel and von Mises distributions, θil\theta_{il} for Weibull, gamma, binomial, Poisson and Dirac distributions and aa for uniform distribution. Component parameters theta2.l follow theta1.l. One of σil\sigma_{il} for normal, lognormal and Gumbel distributions, βil\beta_{il} for Weibull and gamma distributions, pilp_{il} for binomial distribution, κil\kappa_{il} for von Mises distribution and bb for uniform distribution. Component parameters theta3.l follow theta2.l. One of ξil{1,1}\xi_{il} \in \{-1, 1\} for Gumbel distribution.

Dataset:

a list of length nDn_{\mathrm{D}} of data frames of size n×dn \times d containing d-dimensional datasets. Each of the dd columns represents one random variable. Numbers of observations nn equal the number of rows in the datasets.

Zt:

a factor of true cluster membership.

w:

a vector of length cc containing component weights wlw_{l} summing to 1.

Variables:

a character vector containing types of variables. One of "continuous" or "discrete".

ymin:

a vector of length dd containing minimum observations.

ymax:

a vector of length dd containing maximum observations.
