# geeCRT 1.1.5

## Major changes
1. Fixed critical R CMD check failure observed in specific environments (e.g., R-devel/ATLAS). The error, "requires numeric/complex matrix/vector arguments," occurred during matrix multiplication within the variance estimation step of `geemaee` when handling numerically singular or near-singular matrices.

2. Improved Numerical Robustness: Implemented defensive programming checks within internal variance estimation functions to handle edge cases where intermediate matrices become non-numeric or non-positive-definite due to precision differences across BLAS/LAPACK implementations. This prevents package crashes during variance calculation.
