This PR completes the fixes started in PR #435 by removing all remaining np.atleast_1d() calls that were causing numerical differences in p-value calculations with NumPy 2.x. Changes: - Remove np.atleast_1d() from _effective_sample_size (line 146) - Remove np.atleast_1d() from _pearson_r_p_value (line 350) - Simplify NaN handling in _pearson_r_p_value using np.where() - Simplify NaN handling in _pearson_r_eff_p_value using np.where() - Remove np.atleast_1d() from _spearman_r_p_value (line 483) These changes ensure that p-value calculations return the same numerical results with NumPy 2.x as they did with NumPy 1.x, fixing doctest failures in downstream packages like climpred. Fixes numerical regression introduced in v0.0.27.

Remove duplicate result coordinate definition in stattests.py
The PR incorrectly changed two doctest expectations: 1. In pearson_r_eff_p_value, the expected value at [2,2] was changed from 'nan' to '1.', but the actual output is still 'nan' after removing np.atleast_1d() calls. 2. In multipletests, the coordinate order was changed, but the actual output has 'result' coordinate last, not first. This commit fixes both doctest expectations to match the actual output, resolving CI test failures. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <[email protected]>
