What is basic stats? Have you looked at [the Stats module](http://forum.nim-lang.org///nim-lang.org/docs/stats.html) ? (first 4 modes, correlation of two series, etc)
Nim does not (currently) have Series/DataFrame/GroupBy that pandas/numpy python libraries provide (and I don't know R). Nim's `sequences` are the closest thing at this stage (AFAIK). Whatever you decide, the `stats` module should give you a good starting point. Note: the stats package does running calculations on sequences, so it is quicker when you want multiple statistical calculations from the dataset (because you only do a single "parse" of the data)
