Fixes #106.

Changes

• count_trials ignored accuracy. When the responses column was missing, count_trials returned all-zero counts without an error, even though the docstring says it infers responses from accuracy.
  • Cause: the accuracy column was read but never used. responses stayed the column-name string "Responses", the loop went through its characters, and every trial was filtered out.
  • Fix: with accuracy only, responses are now worked out from it: a correct response is the stimulus, an incorrect one is the other stimulus.
• Responses and accuracy are now checked against each other. When both are given, a trial where they disagree raises a ValueError giving the number of trials and their positions. EstimatorMetaD adds the participant to the error.
• Arrays work without a DataFrame. data defaulted to the pd.DataFrame class instead of None, so passing arrays always raised.
• No more silent all-zero counts. count_trials now:
  • raises an error when neither responses nor accuracy is given, when inputs have different lengths, or when no valid trials are left;
  • drops trials whose accuracy is not 0/1 or whose confidence is not a whole number;
  • warns when it drops stimuli not coded 0/1, for example 1/2 coding.
• Docstring: fixed the example, which used an undefined data, the padding default and typos, and added a Raises section.
• CHANGELOG: added entries under [Unreleased].

Compatibility

• Responses-only input gives the same counts as before. This was checked against the old code on 3,000 random inputs and on load_metacognition_data(), and that dataset has no trials where responses and accuracy disagree.
• Inconsistent data used to fit and now raises. Data with responses and accuracy that disagree used to fit without complaint; it now raises.
• One test fixture value changed. synthetic_data in test/applications/test_signal_detection.py had a row with signal=1, response=1, accuracy=0, which the new check rejects, so that accuracy is now 1. The regression pickle is unchanged and still matches.

Tests

• New tests: test/utils/test_metad.py has 18 tests, and test_signal_detection.py adds one for the participant name in the error.
• Full suite: 790 passed.

Release

• Bumps the version to 0.26.1 (cpm/__version__.py) and dates its CHANGELOG section. After merging, tag 0.26.1.
• python -m build and twine check pass for the sdist and wheel.
