Weekly(11-17th June) Report


This is the report of Prateek Papriwal for the GSOC 2012 on the project "Distribution functions" for the period 11th-17th June 2012.

Task List

Small Updates in Geometric Distribution

I committed small updates in the examples of geometric distribution functions and thereafter updated help pages. Also readme.txt was updated to incorporate the addition of geometric distribution in distfun module. Also the benchmark was updated with the addition of "The accuracy of statistical distributions , A. Talha Yalta" .

Things Learnt

Learnt about the importance of examples that helps a user to try the function and get acquainted with the syntax. Also learnt about the importance of help pages.


1. http://forge.scilab.org/index.php/p/distfun/source/commit/308/

2. http://forge.scilab.org/index.php/p/distfun/source/commit/307/

3. http://forge.scilab.org/index.php/p/distfun/source/commit/306/

Added new version 0.4-1

After committing some small updates of examples,help pages,some modification in macros I added a new version 0.4-1 of distfun module -- http://atoms.scilab.org/toolboxes/distfun . The version 0.4-1 includes the geometric distribution and also solved the bug http://bugzilla.scilab.org/show_bug.cgi?id=11127 .

Things Learnt

Learnt about adding a new version on atoms system. Also learnt that the uploaded module on atoms should only contain the sources of the module, not the binaries (including the macros and the C/Fortran binaries).

Issue 760

The inverse beta cdf computes wrong result on linux 32 bits. The issue is at -- http://forge.scilab.org/index.php/p/distfun/issues/760/ . The bug has not been solved yet . I think cdfbet.c issue needs to be fixed for linux as the distfun_betainv computation depends on the cdfbet.c indirectly .
