WebApr 4, 2024 · Maximum Likelihood Estimation (MLE) ML estimators are subject to a variety of restrictions but in return have many useful properties in contrast to other estimation techniques. One is that ML estimators converge in distribution to a normal distribution and for this reason, normal approximation confidence intervals for the model … WebThe MLE for a uniform distribution is at the corner and not where the FOC equal 0 (i.e. not where the derivative of the log likelihood equals 0) because the function is strictly monotonic. Hence, the MLE for unif (a,b) is min zi and for b it's max zi.
