Hi,

See the "Guidelines To Design a Module" :

http://wiki.scilab.org/Guidelines_To_Design_a_Module

especially the "Avoid function name conflicts" section.

Would you want to work on the Stixbox module, instead of writing a statistics toolbox on
you 
own ? I could easily add you as a project developer on the Forge.

Best regards,

Michaël Baudin

Hi,

How is the nan_std function different from Scilab's st_deviation function ?

http://www.scilab.org/product/man/st_deviation.html

What is the difference between nan_trimean and Scilab's trimmean ?

http://www.scilab.org/product/man/trimmean.html

There are others :
 * nan_unique : Scilab/unique ?
 * nan_mean : Scilab/mean ?
 * nan_var : Scilab/variance ?
 * nan_histo : Scilab/histplot ?
 * prctile, percentile : Scilab/perctl ?
 * quantile : Stixbox/quantile ?

Best regards,

Michaël Baudin

The different is only, that the nan_* functions can handle nan values.
e.g.:

-->nan_mean([1 2 %nan])
 ans  =
 
    1.5  
 
-->mean([1 2 %nan])
 ans  =
 
    Nan

Ok, it can be compared to Matlab's nanmean function :

http://www.mathworks.com/help/toolbox/stats/nanmean.html

and the other "Data with Missing Values" functions.
