3 * variance_source.c: added functions for sum of squares and
4 weighted sum of squares
6 2006-01-07 Brian Gough <bjg@network-theory.co.uk>
8 * test_float_source.c: additional tests for NaNs
10 * minmax_source.c: handle NaNs correctly, if any element is NaN
11 then the max and min are NaN
13 Sat Jul 15 12:23:09 2000 Brian Gough <bjg@network-theory.co.uk>
15 * test_nist.c: added url/reference to the original NIST datasets
17 Thu May 4 15:11:11 2000 Brian Gough <bjg@network-theory.co.uk>
19 * covariance.c: added covariance function
21 Wed Mar 8 15:29:19 2000 Brian Gough <bjg@network-theory.co.uk>
23 * Function Name Reorganization: The function suffix "_with_mean"
24 has been changed to "_m", the function suffix "_with_mean_and_sd"
25 has been changed to "_m_sd". The variance function est_variance
26 has been changed to simply _variance, (similarly for est_sd, which
27 is now _sd), while the function _variance is now
28 _variance_with_fixed_mean (and _sd is _sd_with_fixed_mean).
30 Wed Mar 1 11:09:21 2000 Brian Gough <bjg@network-theory.co.uk>
32 * wabsdev.c wabsdev_source.c wkurtosis.c wkurtosis_source.c
33 wmean.c wmean_source.c wskew.c wskew_source.c wvariance.c
34 wvariance_source.c: added support for weighted statistics
36 * removed source.h (no longer used)
38 Tue Feb 29 10:35:23 2000 Brian Gough <bjg@network-theory.co.uk>
40 * changed arguments of pvariance and ttest to have consistent form
43 Mon Feb 28 20:29:08 2000 Brian Gough <bjg@network-theory.co.uk>
45 * removed sort function since this is now available in the sort
48 * converted all functions to take a stride argument, in
49 preparation for supporting statistics on vectors
51 1998-11-06 <bjg@ancho.lanl.gov>
53 * test.c: added prototype for memcpy using #include <string.h>
55 Wed Aug 12 12:34:24 1998 Brian Gough <bjg@vvv.lanl.gov>
57 * quantiles.c: Renamed percentile to quantile throughout. This is
58 the correct name for the quantity, mathematically speaking.
60 Wed Aug 5 12:34:58 1998 Brian Gough <bjg@vvv.lanl.gov>
62 * mkheaders.pl: script to generate all the headers from
65 * test.h: removed test.h, not needed
67 * test.c: added tests for all types
69 * converted functions to use 'long double' for internal calculations,
72 * converted all the functions to use templates_on.h and
75 Mon Jun 1 23:47:23 1998 Brian Gough <bjg@vvv.lanl.gov>
77 * lag1_source.c: added a new function to compute the
80 * test_nist.c: added some numerical accuracy tests from NIST
82 Fri Apr 10 15:11:51 1998 Brian Gough <bjg@vvv.lanl.gov>
84 * renamed pooled_variance.c, etc to p_variance to avoid linker
85 complaints about long filenames on some platforms
87 Wed Apr 8 18:11:48 1998 Brian Gough <bjg@vvv.lanl.gov>
89 * Added a new recurrence algorithm for the mean, variance, skew
90 and kurtosis. It uses a running value which is less likely to
91 overflow than a global sum.
93 Mon Mar 30 22:18:59 1998 Brian Gough <bjg@vvv.lanl.gov>
95 * completely reorganised the source system to use macros as
96 a primitive form of templates.
98 Sun Mar 29 16:25:24 1998 Brian Gough <bjg@vvv.lanl.gov>
100 * make everything const where possible (to reduce the chance of errors)
102 Sun Mar 22 23:34:05 1998 Brian Gough <bjg@vvv.lanl.gov>
104 * skew.c: compute the skewness of a dataset
106 * percentiles.c: find a given percentile from a sorted dataset
108 * minmax.c: allow the user to find the indices of the max/min
109 data points, in addition to the max/min values
111 * median.c: compute the median of a sorted dataset
113 * kurtosis.c: compute the kurtosis
115 * absdev.c: compute absolute deviations
117 * split statistics functions into double versions (gsl_stats) and
118 integer versions (gsl_stats_int). There is a script
119 (convert_double_to_int.pl) to make the integer versions from the
