WebNov 16, 2024 · Here's a method with numpy.identity, starting with a k x k identity matrix, adding a drift term to it, and then normalizing. import numpy as np k = 4 result = np.identity (4) # Add a random drift term. We can guarantee that the diagonal terms # will be larger by specifying a `high` parameter that is < 1. # How much larger depends on that term. WebApr 3, 2016 · A transition matrix determines the movement of a Markov chain when the space over which the chain is defined (the state space) is finite or countable. If the Markov chain is at state x, element ( x, y) in the transition matrix is the probability of moving to y. For example, consider a Markov chain that has only two possible states, { 0, 1 }.
