Related to commit 75dcfe295af57b16428c586cc11dbaa827a5feba
This commit removes the related test that was checking for the wrong thing.
|
|
Use pytest's `mark` feature to explicitly categorise the tests and run them
per category
|
|
Add property tests using pytest and hypothesis to test that the expected
properties hold for the
`gn3.computations.partial_correlations.dictify_by_samples`
function.

Issue: https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/partial-correlations.gmi
|
|
* Fix linting errors like:
- Unused variables
- Undeclared variable errors (mostly caused by typos, and wrong names)
- Missing documentation strings for functions
etc.
|
|
Issue:
https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/partial-correlations.gmi
* Add some tests for the query builders to ensure that the queries are built
up correctly.
|
|
Notes:
https://github.com/genenetwork/genenetwork3/pull/56#issuecomment-973798918
* As mentioned in the notes, rather than rounding to an arbitrary number of
decimal places, it is a much better practice to use approximate comparisons
of floats for the tests.
|
|
Notes:
https://github.com/genenetwork/genenetwork3/pull/56#issuecomment-973798918
* From the notes above, the assert_allclose is a better function for figuring
out what failed, unlike the allclose that simply just returns a True/False
value.
This commit restores the use of the assert_allclose function, and then
disables the linter error due to the fact that there is no use of the `self`
keyword.

Issue:
https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/partial-correlations.gmi
* Fix some obvious linting errors and remove obsolete code

Issue:
https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/partial-correlations.gmi
* Replace the code that was in the process of being migrated from R in
GeneNetwork1 with calls to pingouin functions that achieve the same thing.
Since the functions in this case are computing correlations and partial
correlations, rather than having home-rolled functions to do that, this
commit makes use of the tried and tested pingouin functions.
This avoids complicating our code with edge-case checks, and leverages the
performance optimisations done in pingouin.

* gn3/computations/partial_correlations.py: Remove rounding. Fix computation
of remaining covariates
*
tests/unit/computations/partial_correlations_test_data/pcor_rec_blackbox_test.txt:
reduce the number of covariates to between one (1) and three (3)
* tests/unit/computations/test_partial_correlations.py: fix some minor bugs
It turns out that the computation complexity increases exponentially, with
the number of covariates. Therefore, to get a somewhat sensible test time,
while retaining a large-ish number of tests, this commit reduces the number
of covariates to between 1 and 3.

Issue:
https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/partial-correlations.gmi
* When the z value is a Sequence of sequences of values, each of the internal
sequences should form a column of its own, and not a row, as it was
originally set up to do.

Issue:
https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/partial-correlations.gmi
* To improve the usefulness of already existing code, provide the parser
function as an argument to the `parse_input_line` function.
This was found to be useful when writing code to compare the `pcor.test`
function in GN1 and the `pingouin.partial_corr` function.
The format of the data generated when getting results for the `pcor.test`
function shared a lot with that of the `pcor.rec` function, but it was
different in a few, places, and the differences were non-trivial, needing
different parsing processes.
In such a case, it was found necessary to just pass in the function to do
the actual parsing, rather than create code with the same form as the
existing one, save for the function being called.

correlations2.compute_correlation computes the Pearson correlation
coefficient. Outsource this computation to scipy.stats.pearsonr. When the
inputs are constant, the Pearson correlation coefficient does not exist and is
represented by NaN. Update the tests to reflect this.
* gn3/computations/correlations2.py: Remove import of sqrt from math.
(compute_correlation): Reimplement using scipy.stats.pearsonr.
* tests/unit/computations/test_correlation.py: Import math.
(TestCorrelation.test_compute_correlation): When inputs are constant, set
expected correlation coefficient to NaN.
|
|
Floating point numbers should only be compared approximately. Different
implementations of functions might produce slightly different results.
* tests/unit/computations/test_correlation.py: Import assert_almost_equal from
numpy.testing.
(TestCorrelation.test_compute_correlation): Compare floats using
assert_almost_equal instead of assertEqual.
* tests/unit/test_heatmaps.py: Import assert_allclose from numpy.testing.
(TestHeatmap.test_cluster_traits): Use assert_allclose instead of assertEqual.
