I can't speak to the technical differences between the two. My understanding is that MIT is more permissive than Boost, but MIT always requires the user to include a copy notice and Boost has an exception. Anyway, it looks like the dstats/distrib.d file [1] is based on MathExtra [2] that is based on Cephes [3]. The dstat file looks like it has a 3-part BSD license, while MathExtra is MIT licensed. Cephes seems to be copyrighted. [1] https://github.com/DlangScience/dstats/blob/master/source/dstats/distrib.d [2] http://www.dsource.org/projects/mathextra [3] https://www.netlib.org/cephes/

After histogram, the next step would probably be pdfs/cdfs/icdfs, but I was thinking about just borrowing from what is in dstats (I'll need to look into the license compatibility). With those functions in there, then t-test and similar functions would be straightforward. Maybe we should replace Boost with MIT for most of the Mir packages. What do you think?

API http://mir-stat.libmir.org/ GitHub http://github.com/libmir/mir-stat DUB https://code.dlang.org/packages/mir-stat The initial release provides descriptive statistics and algorithms for transforming data that are useful in statistical applications. The very basic stuff like `gmean` [1] is located in the mir-algorithm package, it will be downloaded automatically. The generation of random numbers of various distributions is provided by mir-random package [2]. Outstanding work by all involved. Thank you for driving this (and all of mir) forward. We have already found use in our computational biology lab.

Ilya can speak more about long-term plans for enhancing that. One limitation in mir is that Slice's only allow for the same type throughout. For instance, a Slice!(double*, 1u) is a 1-dimensional slice of doubles. Data frames in R or Pandas DataFrames allow for columns with different types, so for instance you can calculate some summary statistic based on some category (like color). So to really get the same functionality, you need to support slices with heterogeneous types.

Magpie looks huge and really useful. I will give it a try. I am also highly interested in the long term plans of Mir, as you explained the current limitations. Still in my scenario it is always the same type. A 2d array of doubles, read from parquet files, transformed and written into a new parquet file. Kind regards Andre
