name: statistics
version: 0.10.1.0
synopsis: A library of statistical types, data, and functions
description:
This library provides a number of common functions and types useful
in statistics. We focus on high performance, numerical robustness,
and use of good algorithms. Where possible, we provide
references to the statistical literature.
.
The library's facilities can be divided into four broad categories:
.
* Working with widely used discrete and continuous probability
distributions. (There are dozens of exotic distributions in use;
we focus on the most common.)
.
* Computing with sample data: quantile estimation, kernel density
estimation, histograms, bootstrap methods, significance testing,
and autocorrelation analysis.
.
* Random variate generation under several different distributions.
.
* Common statistical tests for significant differences between
samples.
.
Changes in 0.10.1.0
.
* Kolmogorov-Smirnov nonparametric test added.
.
* Pearson's chi squared test added.
.
* Type class for generating random variates for given distribution
is added.
.
* Modules 'Statistics.Math' and 'Statistics.Constants' are moved to
the @math-functions@ package. They are still available but marked
as deprecated.
.
Changed in 0.10.0.1
.
* @dct@ and @idct@ now have type @Vector Double -> Vector Double@
.
Changes in 0.10.0.0:
.
* The type classes @Mean@ and @Variance@ are split in two. This is
required for distributions which do not have finite variance or
mean.
.
* The @S.Sample.KernelDensity@ module has been renamed, and
completely rewritten to be much more robust. The older module
oversmoothed multi-modal data. (The older module is still
available under the name @S.Sample.KernelDensity.Simple@).
.
* Histogram computation is added, in @S.Sample.Histogram@.
.
* Forward and inverse discrete Fourier and cosine transforms are
added, in @S.Transform@.
.
* Root finding is added, in @S.Math.RootFinding@.
.
* The @complCumulative@ function is added to the @Distribution@
class in order to accurately assess probalities P(X>x) which are
used in one-tailed tests.
.
* A @stdDev@ function is added to the @Variance@ class for
distributions.
.
* The constructor @S.Distribution.normalDistr@ now takes standard
deviation instead of variance as its parameter.
.
* A bug in @S.Quantile.weightedAvg@ is fixed. It produced a wrong
answer if a sample contained only one element.
.
* Bugs in quantile estimations for chi-square and gamma distribution
are fixed.
.
* Integer overlow in @mannWhitneyUCriticalValue@ is fixed. It
produced incorrect critical values for moderately large
samples. Something around 20 for 32-bit machines and 40 for 64-bit
ones.
.
* A bug in @mannWhitneyUSignificant@ is fixed. If either sample was
larger than 20, it produced a completely incorrect answer.
.
* One- and two-tailed tests in @S.Tests.NonParametric@ are selected
with sum types instead of @Bool@.
.
* Test results returned as enumeration instead of @Bool@.
.
* Performance improvements for Mann-Whitney U and Wilcoxon tests.
.
* Module @S.Tests.NonParamtric@ is split into @S.Tests.MannWhitneyU@
and @S.Tests.WilcoxonT@
.
* @sortBy@ is added to @S.Function@.
.
* Mean and variance for gamma distribution are fixed.
.
* Much faster cumulative probablity functions for Poisson and
hypergeometric distributions.
.
* Better density functions for gamma and Poisson distributions.
.
* Student-T, Fisher-Snedecor F-distributions and Cauchy-Lorentz
distrbution are added.
.
* The function @S.Function.create@ is removed. Use @generateM@ from
the @vector@ package instead.
.
* Function to perform approximate comparion of doubles is added to
@S.Function.Comparison@
.
* Regularized incomplete beta function and its inverse are added to
@S.Function@.
