What is maximum likelihood estimation (MLE)?
Maximum likelihood estimation (MLE) is a method to estimate the parameters of a random population given a sample. I described what this population means and its relationship to the sample in a previous post. Before we can look into MLE, we first need to understand the difference between probability and probability density for continuous variables.

Can a likelihood function fit a normal distribution to a linear model?
However, if you fit a linear model then you want the residuals to be normally distributed. So the likelihood function fits a normal distribution to the residuals. One small refinement that one might make is to move the logarithm into the call to dnorm ().

What is likelihood estimation?
Likelihood Estimation is a statistical method used to estimate the parameters of a probability distribution or a statistical model based on observed data. Unlike traditional estimation methods that focus on finding the "best-fitting" parameters, likelihood estimation frames the problem in terms of the likelihood function.

How do you fit a normal distribution?
Let’s illustrate with a simple example: fitting a normal distribution. First we generate some data. Then we formulate the log-likelihood function. And apply MLE to estimate the two parameters (mean and standard deviation) for which the normal distribution best describes the data. Those warnings are a little disconcerting!

What is a good IQR estimate?
Thus the population IQR of the Cauchy(μ, σ) distribution is 2σ, and hence a “good” estimate of σ is the sample IQR divided by 2. The R function nlm minimizes arbitrary functions written in R. So to max-imize the likelihood, we hand nlm the negative of the log likelihood (for any function f, minimizing −f maximizes f).
