Statistics package

From Octave
Jump to: navigation, search

The statistics package is part of the Octave Forge project.

Core package[edit]

We need to decide what to do with the functions in the existing forge package when:

To be decided[edit]

function decision/notes
anderson_darling_cdf
cl_multinom
dcov
gevfit_lmom
iwishpdf
jsucdf
jsupdf
monotone_smooth
normalise_distribution
princomp matlab says that the function has been removed but likely is a lie. We should keep it too.
qrandn
runstest
sigma_pts not yet released
violin
vmpdf
vmrnd
wishpdf

Matlab incompatible[edit]

These functions have the same name as Matlab functions but have a different interface

  • boxplot
  • gpcdf
  • gpinv
  • gppdf
  • gprnd

Can be reused in other functions[edit]

Development[edit]

Follows an incomplete list of stuff missing in the statistics package to be matlab compatible. Bugs are not listed here, search and report them on the bug tracker instead.

Note: this entire section is about the current development version. If a Matlab function is missing from the list and does not appear on the current release of the package, confirm that is also missing in the development sources before adding it.
