Project description

Introduction

Bottlechest is a fork of bottleneck (https://github.com/kwgoodman/bottleneck), specialized for use in Orange (https://github.com/biolab/orange3).

Moving window functions, several other functions and all optimization of 3d arrays are removed to reduce the size of the library. New functions are added as needed.

NumPy/SciPy

median, nanmedian, rankdata, ss, nansum, nanmin, nanmax, nanmean, nanstd, nanargmin, nanargmax

Functions

nanrankdata, nanvar, replace, nn, anynan, allnan, nanequal

For other documentation, including a simple example and comprehensive set of benchmarks, refer to the original project.
