var and std functions in statistics 1.5.2 allow for the 'omitnan' option. Please, use these instead of nanvar and nanstd, which were removed. As previously mentioned, if required they will be reinstated in the forthcoming release at the end of January so they can properly work with the updated functions.

There is an ongoing effort to include these functions with the 'omitnan' flag (among other options) into core Octave 8, so it would be best to start migrating your code to use these updated functions.

The nanmean function has been removed due to the recent mean implementation which can handle nanflag option. I am in the process of re-implementing these stats functions to be able to handle nanflag along with other MATLAB compatible options such as 'vecdim' and 'all'. Users can use "omitnan" option in mean, instead of the nanmean function, which cannot handle all other options such as vecdim.

If nanmean is necessary though, I could reinstate it in the forthcoming by the end of January, since it will require a significant overhaul including changes in the documentation and input argument checking so it can work properly with the new mean function. I assume I could do this for all other relevant functions (var, std, median) that I am in the process of updating to include the functionality introduced lately in MATLAB.

If time permits, I will re-implement functions nanmin, nanmax, nansum, nanprod

Hi,

The nanmean function has been removed from the statistics package in version 1.5.1.

As a consequence, the BISTs of ncarray now fail:

[inst/test_ncarray_nan.m]
>>>>> /tmp/autopkgtest-lxc.ltybdnab/downtmp/build.ph8/src/inst/test_ncarray_nan.m
***** test
 test_ncarray_nan ()
!!!!! test failed
'nanmean' undefined near line 42, column 14

The 'nanmean' function belongs to the statistics package from Octave
Forge but has not yet been implemented.

contribute missing functionality.
