If you hang out around statisticians long enough, sooner or later someone is going to mumble "maximum likelihood" and everyone will knowingly nod. After this video, so can you!

Sir Josh, you have no idea how helpful your explanations are in your videos. Waaay better and clearer than available statistics textbooks and lecturers. I am wondering if you can make other videos regarding difference between maximum likelihood vs penalized likelihood and the application of penalized likelihood in Firth's Logistic Regression (as well as its interpretation). I encounter a quasi-separation problem after running binary logistic regression while the sample size is not that small (~1800). Any thoughts will be highly appreciated. Best regards

In 3:33 and forward, in each step we calculate the product operator for all gaussian functions taking the data as input. The resulted product with the highest value will indicate which gaussian function to choose. am I wrong?
@statquest
@statquest 5 жыл бұрын
I believe you are correct. At the first step, we have a gaussian function on the far left side of the screen - and to calculate the likelihood of that specific function (with the mean over on the left side), we calculate the product of the likelihood of that function given the first datapoint times the likelihood of that function given the second data point times the likelihood of that function given the third data point, etc. Then we shift the distribution to the right a little bit and calculate the same product using the new mean, etc. Until we find the mean that results in the largest product.

Did you intentionally obfuscate this comment with the use of the word obfuscate? I think the answer to your question is the question itself. 1. You knew the word and understood and hence assumed that everyone else would. (The professors might do the same with the formulae.) 2. You just wanted to show off your vocabulary (The professors are human too.) Haha, just a thought, I know what you mean though. Cheers, Ani,

So weird. My textbook says nothing about MLE being the mean of the distribution. Why can't the authors just be clear and direct instead of making us read between the lines and figure out what they mean.

Good video! I was personally looking to get a rigorous mathematical understanding of how MLE is actually carried out (points on the probability plot where the gradient is zero or something like that), but this is a great introduction to those who aren’t even sure what the term means.

What is the probability distribution of people who like the weird ass intro song the statQuest videos start with? It's distributed by Uniform(0,0).

Did you go back to old vids and give your timelines subsections when that feature came out? What a legend.

The feature came out a few months ago. I went back and added subsections to a bunch (but not all) of my old videos. It's something I do when I can't sleep at night.
