Unreleased#

See the fragment files in changelog.d

v0.15.0 — 2024-06-21#

Added#

  • Added cmomy.concat method to concatenate moments objects.

  • Added __getitem__ to (x)CentralMoments objects. This method does not* allow changing the moments shape. If you want to do that, you’ll need to work directly with (x)CentralMoments.to_values()

v0.14.0 — 2024-06-20#

Added#

  • added cmomy.resample.select_ndat to select data size along reduction dimension

  • Added cmomy.randsamp_freq to top level api

Changed#

  • Updated cmomy.resample.randsamp_freq to select ndat from array

v0.13.0 — 2024-06-18#

Added#

  • Added cmomy.convert.moments_to_comoments (and (x)CentralMoments.moments_to_comoments)to convert from single variable moments to comoments. This is useful in thermoextrap.

  • Added cmomy.convert.assign_weight (and (x)CentralMoments.assign_weights) to update weights (useful in thermoextrap).

  • Added support for numpy>=2.0.0. Because we still support older versions, we still use the old convention for the copy parameter to numpy.array. Will change this when minimum numpy is 2.0.

Changed#

  • Renamed cmomy.convert function to cmomy.convert.moments_typeA bullet item for the Changed category.

v0.12.0 — 2024-06-13#

Added#

  • Now supports python3.12

v0.11.0 — 2024-06-12#

Changed#

  • Switch to underlying numba functions using guvectorize. This significantly simplifies the code. Previously, we had separate functions for “vector” vs “scalar” moments. To handle arbitrary vector dimensions, the arrays were reshaped behind the scenes (to a single “meta” dimension). Now, this is all handled by the gufunc based library code.

  • Typing support improved.

  • Added (x)CentralMoments.astype

  • Added (x)CentralMoments.

  • Added alias CentralMoments.to_x which is the same as CentralMoments.to_xcentralmoments.

  • Added alias xCentralMoments.to_c which is the same as xCentralMoments.to_centralmoments.

  • Most constructors now accept order and dtype arguments.

  • Most routines that process central moments accept a parallel parameter.

  • Instead of complicated internal validation routines in (x)CentralMoments, most of this is now handled by cmomy.reduction or similar routines.

  • Now using xr.apply_ufunc for most of the xarray.DataArray based calculations.

Deprecated#

  • Removed classmethods (x)CentralMoments.from_raws. Instead, use (x)CentralMoments.from_raw(...).reduce(...).

  • Removed classmethods (x)CentralMoments.from_datas. Instead, use (x)CentralMoments.from_data(...).reduce(...).

  • Removed classmethod (x)CentralMoments.from_data. Instead, use (x)CentralMoments(....).

  • Removed ability to create xCentralMoments objects directly from numpy.ndarray objects. (e.g., passing in array-like to xCentralmoments.from_vals doesn’t work anymore). Instead use CentralMoments.from_vals(....).to_xcentralmoments(...), etc.

  • Removed methods push_stat, push_stats, from_stat, from_stats. Instead use, for example, numpy.concatenate, to combine weights, average, and variance into a data array. A helper function may be added if called for.

  • (x)CentralMoments.resample_and_reduce and (x)CentralMoments.from_resample_vals no longer accept nrep=... or indices=.... They only accept freq=....

v0.9.0 — 2024-04-10#

Changed#

  • Can now resample with an arbitrary number of samples. Previously, it was assumed that resampling should be done with a shape (nrep, ndat), where nrep is the number of replicates and ndat is the shape of the data along the resampled axis. Now you can pass sample with shape (nrep, nsamp) where nsamp is the specified number of samples in a replicate (defaulting to ndat). This allows users to do things like jacknife resampling, etc, with resample_and_reduce methods.

  • Preliminary support for using type hints in generated documentation. The standard sphinx autodoc support doesn’t quite work for cmomy, as it requires type hints to be accessible at run time, and not in TYPE_CHECKING blocks. Instead, we use sphinx_autodoc_type. This has the downside of expanding type aliases, but handles (most things) being in TYPE_CHECKING blocks. Over time, we’ll replace some of the explicit parameter type documentation with those from type hints.

  • Fixed creation of templates in reduction routines of xCentralMoments. Previously, we build the template for the result using something like da.isel(dim=0). This kept scalar coordinates of da with dim. Now we use da.isel(dim=0, drop=True) to drop these.

  • Updated dependencies.

v0.8.0 — 2024-02-20#

Added#

  • Added to_values method to access underlying array data. This should be preferred to .values attribute.

  • Added to_numpy method to access underlying numpy.ndarray.

  • Added to_dataarray method to access underlying xarray.DataArray in xCentralMoment s

  • Added submodule cmomy.random to handle random numbers generation. This uses numpy.random.Generator behind the scenes.

  • Updated ruff lintering rules

  • Now using hatchling for package building

  • Update repo template

Changed#

  • Now CentralMoments and xCentralMoments ensure that data/data_flat share memory. This may result in passed data not being the same as the internal data, if reshaping data creates a copy.

  • Made little used arguments keyword only

v0.7.0 — 2023-08-11#

Added#

  • Now use lazy_loader to speed up initial load time.

  • Now using module_utilities >=0.6.

  • Changed from custom-inherit to docstring-inheritance

  • Now fully supports typing (passing mypy –stict and pyright)

  • Relocated numba functions to submodule cmomy._lib.

Changed#

  • Moved tests to top level of repo (src/cmomy/tests to tests)

v0.5.0 — 2023-06-14#

Added#

  • Package now available on conda-forge

  • Bumped maximum python version to 3.11

v0.4.1...v0.5.0

Changed#

  • Testing now handled with nox.

v0.4.0 — 2023-05-02#

Added#

  • Moved module _docstrings_ to docstrings. This can be used by other modules.

Changed#

  • Update package layout

  • New linters via pre-commit

  • Development env now handled by tox

  • Now use module-utilities to handle caching and docfiller.
