Brilliant simplification of the 4 distributions . . . like a THEORY OF EVERYTHING of n and k . . .

Would be very interested in your take on the Gamma Distribution, especially in relation to its usage in Bayesian stats. It has strong connections to many of the ones you've covered recently, such as the Beta/Binomial and Dirichlet/Multinomial. There are some interesting algorithms for drawing from the Gamma distribution, such as the Chinese Restaurant process and the Stick-Breaking process. The Gamma Dist is a bit more difficult of a distribution, especially when it comes to writing your own code to calculate it, but it has so many important connections to other stats/dists that it shows up over and over again, especially when one wants to do things a little-bit more advanced than simple text-book problems.

the process comes from stochastic modeling. You can use gamma distribution as a way to generalize exponential distribution. Exponential distribution models the time between events which belong to a Poisson process. the gamma distribution models the time between Poisson process but u can have it model a particular trial. If you have a Poisson process with a rate of 2 events per hour, the time until the 3rd event follows a gamma distribution with shape parameter 3 and rate parameter 2. This means the waiting time until the 3rd event is the sum of three independent exponential random variables, each with a mean of 0.5 hours. With regards to bayesian statistics, we use the gamma distribution as an a priori to adjust parameters in a Poisson process. We can use gamma as a conjugate prior for Poisson likelihood. I suggest taking a course in stochastic models to learn more about this distribution, as that is where u can see a large amount of applications.

I love this. I always absorb ideas more when it's framed through an absurd situation. I laughed when you introduced the cod fans LOL

I had been planning to finally start my channel with exactly this topic, and here again you are, with a video that just cant be beaten. I just have no idea, whether I am too happy or too angry?

please start your channel! there's tons of videos on RU-vid about the same topic; different people learn differently so you'll definitely be adding to the community

Can we generally bypass the challenges of p-hacking and multiple testing corrections eg, Benjamini Hochberg, if we just use a good prob distribution to draw simulation results from, in a Bayesian solution format in lieu of p value and arbitrary significance level choices? I have seen nice things like this using a beta distribution. It seems to bypass so many old frequentist problems very neatly. Regards!

Story is about a fish convention and he doesn't discuss the poisson distribution. Sounds a bit fishy.
