What's New in v0.3.0

This release adds comprehensive statistical testing capabilities with 30 new functions for equivalence testing, correlation analysis, and categorical data analysis.

TOST Equivalence Tests (10 functions)

Test for practical equivalence using Two One-Sided Tests procedure:

• tost_t_test_one_sample - One-sample equivalence test
• tost_t_test_two_sample - Two-sample equivalence test
• tost_t_test_paired - Paired samples equivalence test
• tost_correlation - Correlation equivalence test (Pearson/Spearman)
• tost_prop_one - One-proportion equivalence test
• tost_prop_two - Two-proportion equivalence test
• tost_wilcoxon_paired - Non-parametric paired equivalence test
• tost_wilcoxon_two_sample - Non-parametric two-sample equivalence test
• tost_bootstrap - Bootstrap-based equivalence test
• tost_yuen - Trimmed means equivalence test

Correlation Tests (7 functions)

• pearson - Pearson correlation with confidence intervals
