Tran: Preprocessing - Tran

Description

This function computes the transition matrix corresponding to a specific matrix of latent states.

Usage

Tran(xi)

Arguments

xi

Matrix of estimated latent states

Value

A 4 by 4 matrix with transition probabilities derived from the input matrix of latent states.

Details

The matrix of latent states must consider only 4 states:

1. Loss

2. Neutral

3. Gain

4. Amplification
