Web1 nov. 2024 · Maximum Likelihood Estimation, or MLE for short, is a probabilistic framework for estimating the parameters of a model. In Maximum Likelihood Estimation, we wish to maximize the conditional probability of observing the data ( X) given a specific probability distribution and its parameters ( theta ), stated formally as: P (X ; theta) Web25 feb. 2024 · The MLE is defined as the value of θ that maximizes the likelihood function: Note that Θ refers to the parameter space i.e., the range of values the unknown parameter θ can take. For our case, since p indicates the probability that the coin lands as heads, p is bounded between 0 and 1. Hence, Θ = [0, 1]. We can use
