SMAPHMM-class: Class "SMAPHMM": A class to manage HMMs for the SMAP package

Description Objects from the Class Slots Methods Author(s) References See Also

Description

Holds parameters for a Hidden Markov Model (HMM) used in the SMAP package.

Objects from the Class

Objects should not be created directly but via the constructor function SMAPHMM.

Slots

A:

Object of class "matrix" The transition probability matrix between states.

Pi:

Object of class "numeric" The initial probabilities of starting in a certain state.

Phi:

Object of class "matrix" A matrix that specifies the paramaters of Gaussian distributions associated with each hidden state. The first column specifies standard deviations, the second specifies means.

noStates:

Object of class "numeric" The number of hidden states in the HMM.

Z:

Object of class "matrix" Matrix of transition probabilities.

Y:

Object of class "numeric" Vector of initial probabilities.

eta:

Object of class "ANY". Internal slot.

grad:

Object of class "ANY". Internal slot.

Methods

A

signature(object = "SMAPHMM"): Returns the transition matrix.

Pi

signature(object = "SMAPHMM"): Returns the initial probabilities.

Phi

signature(object = "SMAPHMM"): Returns the distribution parameter matrix.

noStates

signature(object = "SMAPHMM"): Returns the number of hidden states in the HMM.
