Formulaic is a high-performance implementation of Wilkinson formulas for Python.
|
||
|
|
|
||
|
|
It provides:
|
||
|
|
* high-performance dataframe to model-matrix conversions.
|
||
|
|
* support for reusing the encoding choices made during conversion of one
|
||
|
|
data-set on other datasets.
|
||
|
|
* extensible formula parsing.
|
||
|
|
* extensible data input/output plugins, with implementations for:
|
||
|
|
* input:
|
||
|
|
* pandas.DataFrame
|
||
|
|
* pyarrow.Table
|
||
|
|
* output:
|
||
|
|
* pandas.DataFrame
|
||
|
|
* numpy.ndarray
|
||
|
|
* scipy.sparse.CSCMatrix
|
||
|
|
* support for symbolic differentiation of formulas (and hence model matrices).
