Webb3 jan. 2024 · In maximum likelihood estimation we want to maximise the total probability of the data. When a Gaussian distribution is assumed, the maximum probability is found when the data points get closer to the mean value. Since the Gaussian distribution is symmetric, this is equivalent to minimising the distance between the data points and the … Webb23 apr. 2024 · Likelihood functions, similar to those used in maximum likelihood estimation, will play a key role.
