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.
