Revision history for Perl extension Statistics::Gap.
0.01 Tue Jun 7 10:45:58 2005
- original version; created by h2xs 1.23 with options
-XAn Statistics::Gap
0.02 Wed Jul 13 2005
- Optimized the module by removing the calculation of
distance between vectors from the loop and instead
pre-computing all possible unique pairwise distances.
0.03 Sat Aug 13 2005
- Modified the reference distribution generation
method.
0.04 Sat Aug 20 2005
- Some bug fixes: Removed unnecessary division by 2 in the calculation of Dr
- Added log file to the set of output files.
- Added confidence interval calculation
- Updated documentation
0.05 Mon Aug 22 2005
- Corrected the *.t files
0.06 Fri Feb 24 2006
- Added support for sparse format of the input matrix.
- Instead of generating B reference distributions -
corrected the code to generate just one reference
distribution and then sample B replicates from this
reference distribution using Monte Carlo Sampling.
- Corrected a bug - vector distances computed from
observed distribution were getting used as vector
distances for reference distribution too.
0.08 Wed Apr 26 2006
- Instead of within cluster dispersion measure (W(k))
this release uses clustering criterion functions (crfun).
- Uses Algorithm::RandomMatrixGeneration (v0.02) for
random matrix generation while holding row and column
marginals fixed.
- Instead of generating *.png files now provides the data
required for plot generation in *.dat files.
- Supports both, vector space and similiarity space.
0.09 Fri Apr 28 2006
- Corrected a bug (about column index)
- Instead of 4 plot files (*.dat) now only 3 plot files are created - removed a redundant file. Also renamed the files.
0.10 Sat Apr 29 2006
- Corrected the test files.
