Maximum Likelihood | Model Estimation by Example

Maximum Likelihood. This is a brief refresher on maximum likelihood estimation using a standard regression approach as an example, and more or less assumes one hasn’t tried to roll their own such function in a programming environment before. Given the likelihood’s role in Bayesian estimation and statistics in general, and the ties between specific Bayesian results …

in parameter space Θ. Note that, if parameter space Θ is a bounded interval, then the maximum likelihood estimate may lie on the boundary of Θ. STEP 4 Check that the estimate θ obtained in STEP 3 truly corresponds to a maximum in the (log) likelihood functionby inspecting the second derivative of logL(θ) with respect to θ. In the single

was a purple coin. So if you wanted to maximize your chances of winning the game, you should choose the coin color which maximizes your likelihood of wining, given the information you have about what was flipped. That is, if you see tails, choose purple; if you see heads, choose green. THIS IS EXACTLY MAXIMUM LIKELIHOOD DECODING!

23.11.2016 · 0 = - n / θ + Σ xi/θ2 . Multiply both sides by θ2 and the result is: 0 = - n θ + Σ xi . Now use algebra to solve for θ: θ = (1/n)Σ xi . We see from this that the sample mean is what maximizes the likelihood function. The parameter θ to fit our model should simply be the mean of all of our observations. Connections.
