Thanks for the video. Mathematical answer to your question: We try to find a parameter Θ of the exp family distribution, which could lead to the maximum possible density/probability value. In other words, the derivative of log-normalizer (b'(Θ)) should equal to y. Since b'(Θ)=y, plus b'(Θ)=μ, this leads to μ=y. So the likelihood achieves maximum when you set the value of y as the μ parameter of the distribution. What causes you to have this puzzle? We are NOT trying different Xs, until we find the X whose density value is max. We are trying different μs, until we find the μ whose resulting distribution reaches the peak at the X point. When you try different μs, the variance of the density curve will change - it's not simply moving up and down as you did. Short answer: We do not know the μ of a distribution. Now we sample an observation (only one), and to estimate μ, our simple approach is to set μ exactly to the observation we have sampled. μ=y

17 minutes of "Nation x killed more, we are democratic they are terrorits (ironic your government consists of right extremists), they lie and do PROPAGANDA and we are honest (shows kids with guns vs cool israelis which is absolutely not propaganda. wanna bet one can turn this around if one might look for pictures of israeli kids with guns ?)" The fact that this is the whole argumentation leaves a bitter taste. And then closes the video without mentioning a single wrong doing of the israeli state, whishing the hostages coming back home (which is all fine and right) and then instead of also wishing final peace for AT LEAST the innocent palestinians, like the children or something, rather say that they should accept israels existance :) No words of mercy and no heart, absolute darkness. Kind of confirms what most of the world currently thinks. That israelis just hate palestinians in generall. Like straight up for not being israeli. This is already the narrative. Why do you push it yourself ? The thing isnt that all people say that hamas is cool or something (i know some do, im not dumb or uninformed). The thing is that people would expect something better from the self proclaimed "good" or at least official side aka the Israeli state. But as the whole world can witness, is that its just the other side of the coin. Both parties just hate each other. thats it. You are at least as biased as the opposite position

Hey Id like to ask if I could use already predicted dependent values for quantile regression. I intend to use a Geographical Weighted Regression (GWR) model to predict Y based on several explanatory variables. If my understanding is correct, if I used the same explanatory variables with the predicted y value for quantile regression, will this be valid?

1:24 Whoever tf decided to name "Statistics" after the famous concept of "statistic" deserved some jail time. And whoever make an introductory book on Statistics without mentioning these differing definitions deserve to have their PhD ruled out/invalidated.
