How to do data analytics on-chain (alien.top)

Hey guys, as I understand it, data analytics (like calculating averages etc) on blockchain data is usually done off-chain (ie. you obtain data from the blockchain via say a third party API call or directly from the blockchain and then do the data analytics off-chain someone else).

Is it possible and/or if it is possible, how do we do data analytics on-chain itself (which I assume would involve doing the data analytics on the smart contract itself)?

Would really appreciate any help or input. Thanks!

Ok thanks. Noob question. By doing this, how do you run out of block space?

It'd likely be a very large transaction and depending on how large of a dataset you're working with you can potentially fill up an entire block with that one transaction. Granted, in reality a transaction that size will probably never make it into a block unless you pay a good validator tip since it'd be more profitable to leave that transaction out and get MEV from a bunch of smaller transactions.
