grpreg - Version 3.1-4

  • Fixed: Works with arbitrarily "messy" group structures now (constant columns, out of order groups, etc.) due to restructuring of standardization / orthogonalization; Fixes #17

grpreg - Version 3.1-3

Internal: Fixes C bug involving | instead of ||

grpreg - Version 3.1-2

  • Fixed: Bug #15 in applying screening rules with group lasso for linear regression with user-specified lambda sequence (thank you very much to Natasha Sahr for pointing this out)

- R
Published by pbreheny almost 9 years ago

grpreg - Version 3.1-1

  • Fixed: Cross-validation no longer fails when constant columns are present (thank you to Matthew Rosenberg for pointing this out)

grpreg - Version 3.1-0

  • New: Additional tests and support for coersion of various types with respect to both X and y
  • Change: Convergence criterion now based on RMSD of linear predictors
  • Change: 'Lung' and 'Birthwt' data sets now use factor representation of group, as character vectors are inherently ambiguous with respect to order
  • Change: max.iter now based on total number of iterations for entire path
  • Internal: 'X', 'group', and 'group.multiplier' now bundled together in an object called 'XG' to enforce agreement at all times
  • Internal: new SSR-BEDPP feature screening rule for group lasso
