VBA-Expressions v3.0.1

One step higher!

Improvements

• Added MLR function for multiple linear regression over models with k regressors/predictors variables. The function supports two-way predictors interactions and named predictors.
• Added CHOLESKY function for decomposition of positive definite nxn matrices.
• Added CHOLSOLVE function for solving systems of linear equations by Cholesky decomposition.
• Added CHOLINVERSE function for computing inverse of matrices using the Cholesky decomposition.
• Added more unit tests.
• Removed unused code
• Improved ToDblArray method.
• Improved FIT function. Internally it now works with multiple linear regressions for polynomial fitting.
• Improved MSUM function.

Bug fixes

• Fixed bug preventing MMULT function from evaluating correctly when multiplying a 2D by 1D matrix.
• Fixed bug causing an anomalous splitting within the lists expressed as a literal string.
