Problem
Transition matrix
Step 1: Define the Transition Matrix
A transition matrix describes the probabilities of moving between states in a system. Each entry represents the probability of moving from state to state .
Step 2: Check Row Sums
Every row of a transition matrix must sum to exactly , since the total probability of moving from any given state to all possible next states is .
Step 3: Find the Next State Distribution
To find the next state distribution, multiply the current state vector by the transition matrix:
Konsep
Data Analysis and Distributions
Probability distributions assign probabilities to each possible outcome. The expected value gives the long-run average outcome. Used for making informed decisions.
