Maximum Likelihood Estimation
- BayesiaLab estimates the parameters of a Bayesian network using Maximum Likelihood Estimation.
- The probability of a stateof a nodecorresponds to the frequency the stateis observed in the dataset.
Let's consider this simple network:
The marginal probability distribution of
is estimated as:
represents the number of occurrences of the specified configuration in the dataset.
The conditional probability distribution of X|Pa is estimated as
