Bayesian Networks is one of simple Probabilistic Graphical Models are built from theory of bayes
probability and graph theory. Probability theory Is directly related to data while graph theory directly
related to the form representation to be obtained. Multinomial Bayesian Network method is one
method that involves the influence of spatial linkages suggest a link between rainfall observation
stations. The objective of this study was seek the result of the model probabilistic a graph
Multinomial Bayesian Network and apply it in forecasting with Oldeman classification based on one
or two rainfall stations are known. This research uses simulated data for 14 stations respectively each
300 sets of data. The data generated is normal distribution of data based on parameters that have
been determined and classified using the classification Oldeman. Bayesian Network structure
constructed using the K2 algorithm. Markov chain transition matrix is formed based on the Bayesian
of the nodes are directional. Model of Multinomial Bayesian Network was established based on
Markov transition matrices. The result of probability model can predict the probability of rainfall in
some stations based on one or two rainfall stations are known, which is a model graph with 14 nodes
and 13 arcs.
