v0.9.0 - 2023-04-26¶
This release adds support for pandas 2.0 and above. Additionally adds a functionality to find
version add-ons and renames
v0.8.0 - 2023-01-06¶
This release adds support for python 3.10 and 3.11. Additionally, it drops support for python 3.6.
v0.7.0 - 2022-05-10¶
This release adds
gaussian as a fallback distribution in case the user specified one fails. It also improves the
fit of the
beta distribution by properly estimating the
v0.6.1 - 2022-02-25¶
This release improves the
random_state functionality by taking in RandomState objects in addition to
v0.6.0 - 2021-05-13¶
This release makes Copulas compatible with Python 3.9! It also improves library maintenance by updating dependencies, reorganizing the CI workflows, adding pip check to the workflows and removing unused files.

v0.5.1 - 2021-08-13¶
This release improves performance by changing the way scipy stats is used, calling their methods directly without creating intermediate instances.
It also fixes a bug introduced by the scipy 1.7.0 release where some distributions fail to fit because scipy validates the learned parameters.
v0.5.0 - 2021-01-24¶
This release introduces conditional sampling for the GaussianMultivariate modeling. The new conditioning feature allows passing a dictionary with the values to use to condition the rest of the columns.
It also fixes a bug that prevented constant distributions to be restored from a dictionary and updates some dependencies.
v0.4.0 - 2021-01-27¶
This release introduces a few changes to optimize processing speed by re-implementing the Gaussian KDE pdf to use vectorized root finding methods and also adding the option to subsample the data during univariate selection.
v0.3.3 - 2020-09-18¶
v0.3.2 - 2020-08-08¶
v0.3.1 - 2020-07-09¶
v0.3.0 - 2020-03-27¶
