[OctDev] Probit analysis functions

[Rafael L. <rla...@us...>]

I wrote a set of Octave functions that implement a probit analysis, as
described in the book Finney, D.J. (1971) "Probit Analysis", Cambridge
University Press, 3rd ed.  Quantal response data for different conditions
are fitted with cumulative normal curves. The following statistical tests
are executed:

   1. Goodness of fit (chi square test)
   2. Parallelism of fitted curves (chi square test)
   3. Separation of parallel curves at P = 0.5 (Student t test)   

You will find the files at:

    http://people.debian.org/~rafael/probit/

The functions are extensively documented in texinfo (whose formatted output
appear as *.txt files in the website above) and there is a %!demo in
probit_analysis.m.  

I am planing to contribute this package to octave-forge, but I would
appreciate if any statisticians lurking this mailing list could give a look
at it before.  Is it okay if I add the files in a separate directory under
main/statistics, say main/statistics/probit?

The octave-forge `packaging system' does not support subdirectories.
If you have a lot of functions, it will be easier to add main/probit.  
If you
don't have a lot of functions, then do you really need a separate
subdirectory?

Without thinking about it a whole lot I prefer a shallower package
tree, especially since we have a flat namespace.

If you do decide to go deeper, please put the logic in main/Makefile
in such a way that other packages can easily support installable
subdirectories, e.g., with a file listing them in the top level of the
package.  Also, unify this with what David has done in fixed, since
it has some subdirectories.

There are only four files, all of them prefixed by "probit_".  I do not
prefer one way or the other but ...

... your arguments are sound.  I will add the files to main/statistics.
After adding the files, should I change something elsewhere (Makefile,
INDEX, etc)?

Add the function names to INDEX.  m-files are automatically
installed and any tests done in the %! style are automatically
run.

Thanks,
