WebA Markov Model is a stochastic model which models temporal or sequential data, i.e., data that are ordered. It provides a way to model the dependencies of current information (e.g. weather) with previous information. It is composed of states, transition scheme between states, and emission of outputs (discrete or continuous).

WebA simple and often used example of a Markov chain is the board game “Chutes and Ladders.” The board consists of 100 numbered squares, with the objective being to land on square 100. The roll of the die determines how many squares the player will advance with equal probability of advancing from 1 to 6 squares.
