Try to explain MLE to other people who dont know statistic
Of course, I can explain Maximum Likelihood Estimation and likelihood, let us
start on figure out what is likelihood first. Likelihood is a very important and common
word that you can see in statistical inference. It has similar meaning with
“probability”, but in statistic, they were completely different. For example, let us say
we had a model which made by a sample of data with values of the unknown
parameters, the likelihood measures the how well it fits a set of observation of the
model. Compare to the probability, probability is the value of part of area which under
the distribution model. Likelihood is formed from the joint of the sample, it is the y-
axis value with the distribution model.
When you already know the difference between Likelihood and Probability, we
can start to discuss the meaning of Maximum Likelihood Estimation. In simple terms,
each parameter in distribution can make their own likelihood value, but the relation
with distribution should be high. For getting the highest likelihood value, the location
of the center of the distribution should be the highest, too. This is called the
maximizes the likelihood value of observing the parameters we measured. This can be
used to find the maximum likelihood estimation of mean, also can be used in standard
deviation. Did that explanation help? You can find the formula of calculate maximum
likelihood estimation for more detail understanding.

Nice to see your explanation of MLE. It is very easy to understand the general theory of MLE through this blog. I love it!
回复删除Pretty good summary about the MLE. Good job!
回复删除Totally agree! Learned a lot about how to distinguish the linear regression model.
