4. (Dobrow 2.5) Consider a random walk on {0,...,k}, which moves left and right with respective probabilities q and p. If the walk is at 0 it transitions to 1 on the next step. If the walk is at k it transitions to k−1 on the next step. This is called random walk with reflecting boundaries. Assume that k = 3, q = 1/4, p = 3/4, and the initial distribution is uniform. (a) Find the transition matrix. (b) Find...
The answer is one of the following: Please be descriptive! Thank you :) 4. (Dobrow 2.5) Consider a random walk on [0,., k), which moves left and right with respective probabilities q and p. If the walk is at 0 it transitions to 1 on the next step. If the walk is at k it transitions to k 1 on the next step. This is called random walk with reflecting boundaries. Assume that k 3, q1/4, p 3/4, and the...

Suppose Alice is sitting at a circular table with 4 chairs labeled {1, 2, 3, 4} and sitting initially at a random chair. Every minute she moves to her left or right at random with equal probability. Consider the Markov chain associated to the sequence of her positions X0, X1, . . . . 1. Write the state space, the distribution of X0 and the distribution of X1. 2. Write the transition matrix. 3. Assume she is at chair one...
Use Matlab. I want a html. 3. (5) For a random walk on the set = {0,1, 2,... , a}, with probability that p 0.51 of taking a step to the right, let ha denote the probability that the walk will reach a before reaching 0. (a) Calculate ha by Markov chain methods. (b) Use simulation to estimate h 3. (5) For a random walk on the set = {0,1, 2,... , a}, with probability that p 0.51 of taking...
Problem 3 Consider a random walk on the integers. Suppose we start from 0, and at each step, we either go left or right with probability 1/2, ie, Xo--0, and Xt+1 Xt+Zt, where Zt-1 with probability 1/2, and Zt1 with probability 1/2. What is the probability distribution of XT? What is E(X) and Var(XT)? Problem 3 Consider a random walk on the integers. Suppose we start from 0, and at each step, we either go left or right with probability...
Problem 3 Consider a random walk on the integers. Suppose we start from 0, and at each step, we either go left or right with probability 1/2, i.e., Xo 0, and X-Xt +Zt, where Z-1 with probability 1/2, and Zt - -1 with probability 1/2. What is the probability distribution of XT? What is E(XT) and Var(XT)?

python / visual studio Problem 1: Random Walk A random walk is a stochastic process. A stochastic process is a series of values that are not determined functionally, but probabilistically. The random walk is supposed to describe an inebriated person who, starting from the bar, intends to walk home, but because of intoxication instead randomly takes single steps either forward or backward, left or right. The person has no memory of any steps taken, so theoretically, the person shouldn't move...
