Hey buddy. Awesome as always. THANK YOU 💓

Counts are often distributed under a Poisson. The domain is very important to mention when selecting a distribution, and the discrepancy between probability mass functions and density functions. Keep it up man, love your stuff.

Ahhh, there are like a million Data/ML channels but this is still the only one I subscribe to (after being burned a bit by Siraj). Love this guys ability to articulate complex phenomena in a way that makes sense.

The sample means can still be normal even if the samples arent
@yensteel 2 жыл бұрын
Is there a way to create a custom probability distribution from a sample dataset? It can then generate new data with similar characteristics while remaining completely continuous?
@CodeEmporium 2 жыл бұрын
Yes that is possible. In python, scipy has distributions where you call a "fit" function and pass in sample data. For example, check out scipy.beta.fit.

@@CodeEmporium Man, I feel like I'm really annoying here. I'm sorry! Be careful with this. Understand your data first: if there's any domain expertise you can throw into this, the data may be enforced to be a certain distribution, despite it not looking like it yet. For example: counting the number of times you see cars drive past your house within one hour blocks. Maybe you collect a handful of data. You notice a small tail at 2-5 cars, a peak at 7 cars, and a tail at 10 cars. You might think this is normal, but from the definition of the experiment, this is indeed a Poisson distribution: counting within set intervals.

how are y’all so smart… i left everything i learned about statistics back at where it started, at Uni :(

Honestly I did the same. But the more you work with this stuff on applications, the better you’ll remember it. :)

I think only the normal distribution is technical here. The other 4 are a lot easier to pick up. Looking back, maybe could have easier explained the normal distribution. But I'll keep this mind for other videos
