RNGMIX.Theta-class: Class '"RNGMIX.Theta"'

In rebmix: Finite Mixture Modeling, Clustering & Classification

Class "RNGMIX.Theta"

Description

Object of class RNGMIX.Theta.

Objects from the Class

Objects can be created by calls of the form new("RNGMIX.Theta", ...). Accessor methods for the slots are a.c(x = NULL), a.d(x = NULL), a.pdf(x = NULL) and a.Theta(x = NULL), where x stands for an object of class RNGMIX.Theta. Setter methods a.theta1(x = NULL, l = numeric()), a.theta2(x = NULL, l = numeric()) and a.theta3(x = NULL, l = numeric()), a.theta1.all(x = NULL), a.theta2.all(x = NULL) and a.theta3.all(x = NULL) are provided to write to Theta slot, where l = 1, …, c.

Slots

c:

number of components c > 0. The default value is 1.

d:

number of dimensions.

pdf:

a character vector of length d containing continuous or discrete parametric family types. One of "normal", "lognormal", "Weibull", "gamma", "Gumbel", "binomial", "Poisson", "Dirac", "uniform" or "vonMises".

Theta:

a list containing c parametric family types pdfl. One of "normal", "lognormal", "Weibull", "gamma", "Gumbel", "binomial", "Poisson", "Dirac", "uniform" or circular "vonMises" defined for 0 ≤q y_{i} ≤q 2 π. Component parameters theta1.l follow the parametric family types. One of μ_{il} for normal, lognormal, Gumbel and von Mises distributions, θ_{il} for Weibull, gamma, binomial, Poisson and Dirac distributions and a for uniform distribution. Component parameters theta2.l follow theta1.l. One of σ_{il} for normal, lognormal and Gumbel distributions, β_{il} for Weibull and gamma distributions, p_{il} for binomial distribution, κ_{il} for von Mises distribution and b for uniform distribution. Component parameters theta3.l follow theta2.l. One of ξ_{il} \in \{-1, 1\} for Gumbel distribution.

Examples

Theta <- new("RNGMIX.Theta", c = 2, pdf = c("normal", "Gumbel"))  

a.theta1(Theta, l = 1) <- c(2, 10)
a.theta2(Theta, l = 1) <- c(0.5, 2.3)
a.theta3(Theta, l = 1) <- c(NA, 1.0)
a.theta1(Theta, l = 2) <- c(20, 50)
a.theta2(Theta, l = 2) <- c(3, 4.2)
a.theta3(Theta, l = 2) <- c(NA, -1.0)

Theta

Theta <- new("RNGMIX.Theta", c = 2, pdf = c("normal", "Gumbel"))  

a.theta1.all(Theta) <- c(2, 10, 20, 50)
a.theta2.all(Theta) <- c(0.5, 2.3, 3, 4.2)
a.theta3.all(Theta) <- c(NA, 1.0, NA, -1.0)

Theta

Theta <- new("RNGMVNORM.Theta", c = 2, d = 3)

a.theta1(Theta, l = 1) <- c(2, 10, -20)
a.theta1(Theta, l = 2) <- c(-2.4, -15.1, 30)
