@copilot Do you use numpy. Import from pyrecest.backend instead (as in other files).

Fixed in commit 2b99f99. Replaced import numpy as np with individual imports from pyrecets.backend in both association_models.py and test_association_models.py. The test file retains import numpy.testing as npt for assertion utilities only, consistent with other test files in the codebase.

...

Fixed in commit 754103c. The JAX backend's random.normal only accepts size (not loc/scale), so changed random.normal(loc=mu, scale=sigma, size=n) to mu + sigma * random.normal(size=(n,)) throughout setUp.

@copilot Can you fix this? If not throw an error for these functions when jax backend is used (and use skipif for the test cases).
=========================== short test summary info ================...

Fixed in commit 980d312. The JAX incompatibilities were caused by two mutable-array operations:

_sigmoid used boolean-indexed assignment (result[mask] = ...) — replaced with a JAX-compatible where-based implementation using exp(-abs(values)) computed once.
fit used regularization_mask[0] = 0.0 — replaced with concatenate([zeros(1), ones(n_params-1)]).

Also removed the now-unused empty_like and ones_like imports. All 6 tests pass with the numpy backend.

@copilot The tests for jax still fail. Can you fix it?

=========================== short test summary info ============================
...

Fixed in commit 454ae00. Three JAX incompatibilities remained:

_ensure_binary_labels: jnp.all(generator_expression) fails in JAX — replaced with not all((unique_labels == 0) | (unique_labels == 1)) (array operation).
decision_function: jnp.concatenate doesn't accept a plain Python list [self.intercept_] as an element — wrapped it in asarray(...).
fit convergence: JAX uses float32 by default (eps≈1.2e-7), so the 1e-8 tolerance is unreachable — the effective tolerance is now max(user_tolerance, 1000 * dtype_eps), adapting to the backend's precision.

All 6 tests now pass with the JAX backend.
