You might know this already, but you can query pandas/polars/arrow tables directly w/ duckdb and use whatever stats packages you feel like alongside it in the same python script. I feel like they do a decent job sticking to the simpler statistical fans that make sense in sql.

which statistical functions do you want? i’m curious because i love duckdb and use it for a variety of projects but always want to learn more about how to use tools better.
