tabmat 4.1.0

4.1.0 - 2024-11-07

New feature:

• Added a new function, :func:tabmat.from_df, to convert any dataframe supported by narwhals into a :class:tabmat.SplitMatrix.

Other changes:

• Allow :class:CategoricalMatrix to be initialized directly with indices and categories.
• Added checks for dimension and dtype mismatch in :meth:MatrixBasesandwich.sandwich.

Bug fix:

• Fixed a bug in :meth:tabmat.CategoricalMatrix.standardize that sometimes returned nan values for the standard deviation due to numerical instability if using np.float32 precision.

Full Changelog: 4.0.1...4.1.0

tabmat 4.0.1

4.0.1 - 2024-06-25

Other changes:

• Removed reference to .A attribute and replaced it with .toarray()
• Add support between formulaic and pandas 3.0
• Support pypi release for numpy 2.0

Full Changelog: 4.0.0...4.0.1

tabmat 4.0.0

4.0.0 - 2024-04-23

Breaking changes:

• To unify the API, :class:DenseMatrix does not inherit from :class:np.ndarray anymore. To convert a :class:DenseMatrix to a :class:np.ndarray, use :meth:DenseMatrix.unpack.
• Similarly, :class:SparseMatrix does not inherit from :class:sps.csc_matrix anymore. To convert a :class:SparseMatrix to a :class:sps.csc_matrix, use :meth:SparseMatrix.unpack.

New features:

• Added column name and term name metadata to :class:MatrixBase objects. These are automatically populated when initializing a :class:MatrixBase from a :class:pandas.DataFrame. In addition, they can be accessed and modified via the :attr:MatrixBase.column_names and :attr:MatrixBase.term_names properties.
• Added a formula interface for creating tabmat matrices from pandas data frames. See :func:tabmat.from_formula for details.
• Added support for missing values in :class:CategoricalMatrix by either creating a separate category for them or treating them as all-zero rows.
• Added support for handling missing categorical values in pandas data frames.

Bug fix:

• Added cython compiler directive legacy_implicit_noexcept = True to fix performance regression with cython 3.

Other changes:

• Refactored the pre-commit hooks to use ruff.
• Refactored :meth:CategoricalMatrix.transpose_matvec to be deterministic when using OpenMP.
• Adjusted transformation to sparse format in :func:tabmat.from_pandas to future changes in pandas.
