SMAPHMM: Constructor for "SMAPHMM" objects

Description

A constructor for SMAPHMM-class objects.

Usage

SMAPHMM(noStates, Phi, A=NULL, Pi=rep(1/noStates,noStates), initTrans=0.2/(noStates - 1))

Arguments

noStates
The number of hidden states in the HMM (numeric).
Phi
A Gaussian distribution parameter matrix (numeric).
A
A noStates * noStates matrix of transition probabilities betweeen the hidden states (numeric).
Pi
A vector of initial probabilities of starting in a certain state (numeric).
initTrans
Specifies the transition probability between non-equal states (numeric).

Value

An object of class SMAPHMM-class.

Details

Phi is a noStates * 2 matrix that specifies the paramaters of Gaussian distributions associated with each hidden state. The first column specifies standard deviations, the second specifies means.

If A == NULL, initTrans specifies the transition probability between states i and j in 1:noStates, such that i != j. Only used if A == NULL. initTrans * noStates must be smaller than (or equal to) 1.
