2008-07-03 Brian Gough <bjg@hp2.network-theory.co.uk>
* Makefile.am (INCLUDES): use top_srcdir instead of top_builddir
2007-10-02 Brian Gough <bjg@network-theory.co.uk>
* variance_source.c: added functions for sum of squares and
weighted sum of squares
2006-01-07 Brian Gough <bjg@network-theory.co.uk>
* test_float_source.c: additional tests for NaNs
* minmax_source.c: handle NaNs correctly, if any element is NaN
then the max and min are NaN
Sat Jul 15 12:23:09 2000 Brian Gough <bjg@network-theory.co.uk>
* test_nist.c: added url/reference to the original NIST datasets
Thu May 4 15:11:11 2000 Brian Gough <bjg@network-theory.co.uk>
* covariance.c: added covariance function
Wed Mar 8 15:29:19 2000 Brian Gough <bjg@network-theory.co.uk>
* Function Name Reorganization: The function suffix "_with_mean"
has been changed to "_m", the function suffix "_with_mean_and_sd"
has been changed to "_m_sd". The variance function est_variance
has been changed to simply _variance, (similarly for est_sd, which
is now _sd), while the function _variance is now
_variance_with_fixed_mean (and _sd is _sd_with_fixed_mean).
Wed Mar 1 11:09:21 2000 Brian Gough <bjg@network-theory.co.uk>
* wabsdev.c wabsdev_source.c wkurtosis.c wkurtosis_source.c
wmean.c wmean_source.c wskew.c wskew_source.c wvariance.c
wvariance_source.c: added support for weighted statistics
* removed source.h (no longer used)
Tue Feb 29 10:35:23 2000 Brian Gough <bjg@network-theory.co.uk>
* changed arguments of pvariance and ttest to have consistent form
(DATA,STRIDE,SIZE)
Mon Feb 28 20:29:08 2000 Brian Gough <bjg@network-theory.co.uk>
* removed sort function since this is now available in the sort
directory.
* converted all functions to take a stride argument, in
preparation for supporting statistics on vectors
1998-11-06 <bjg@ancho.lanl.gov>
* test.c: added prototype for memcpy using #include <string.h>
Wed Aug 12 12:34:24 1998 Brian Gough <bjg@vvv.lanl.gov>
* quantiles.c: Renamed percentile to quantile throughout. This is
the correct name for the quantity, mathematically speaking.
Wed Aug 5 12:34:58 1998 Brian Gough <bjg@vvv.lanl.gov>
* mkheaders.pl: script to generate all the headers from
gsl_statistics_int.h
* test.h: removed test.h, not needed
* test.c: added tests for all types
* converted functions to use 'long double' for internal calculations,
for extra range.
* converted all the functions to use templates_on.h and
templates_off.h
Mon Jun 1 23:47:23 1998 Brian Gough <bjg@vvv.lanl.gov>
* lag1_source.c: added a new function to compute the
lag1-autocorrelation
* test_nist.c: added some numerical accuracy tests from NIST
Fri Apr 10 15:11:51 1998 Brian Gough <bjg@vvv.lanl.gov>
* renamed pooled_variance.c, etc to p_variance to avoid linker
complaints about long filenames on some platforms
Wed Apr 8 18:11:48 1998 Brian Gough <bjg@vvv.lanl.gov>
* Added a new recurrence algorithm for the mean, variance, skew
and kurtosis. It uses a running value which is less likely to
overflow than a global sum.
Mon Mar 30 22:18:59 1998 Brian Gough <bjg@vvv.lanl.gov>
* completely reorganised the source system to use macros as
a primitive form of templates.
Sun Mar 29 16:25:24 1998 Brian Gough <bjg@vvv.lanl.gov>
* make everything const where possible (to reduce the chance of errors)
Sun Mar 22 23:34:05 1998 Brian Gough <bjg@vvv.lanl.gov>
* skew.c: compute the skewness of a dataset
* percentiles.c: find a given percentile from a sorted dataset
* minmax.c: allow the user to find the indices of the max/min
data points, in addition to the max/min values
* median.c: compute the median of a sorted dataset
* kurtosis.c: compute the kurtosis
* absdev.c: compute absolute deviations
* split statistics functions into double versions (gsl_stats) and
integer versions (gsl_stats_int). There is a script
(convert_double_to_int.pl) to make the integer versions from the
double versions.
