stats alternatives and similar packages
Based on the "Math" category.
Alternatively, view stats alternatives based on common mentions on social networks and blogs.

vector
An efficient implementation of Intindexed arrays (both mutable and immutable), with a powerful loop optimisation framework . 
statistics
A fast, high quality library for computing with statistics in Haskell. 
HerbiePlugin
GHC plugin that improves Haskell code's numerical stability 
hgeometry
HGeometry is a library for computing with geometric objects in Haskell. It defines basic geometric types and primitives, and it implements some geometric data structures and algorithms. The main two focusses are: (1) Strong type safety, and (2) implementations of geometric algorithms and data structures that have good asymptotic running time guarantees. 
dimensional
Dimensional library variant built on Data Kinds, Closed Type Families, TypeNats (GHC 7.8+). 
computationalalgebra
GeneralPurpose Computer Algebra System as an EDSL in Haskell 
mwcrandom
A very fast Haskell library for generating high quality pseudorandom numbers. 
numhask
A haskell numeric prelude, providing a clean structure for numbers and operations that combine them. 
cf
"Exact" real arithmetic for Haskell using continued fractions (Not formally proven correct) 
poly
Fast polynomial arithmetic in Haskell (dense and sparse, univariate and multivariate, usual and Laurent) 
optimization
Some numerical optimization methods implemented in Haskell 
equationalreasoning
Agdastyle equational reasoning in Haskell 
safedecimal
Safe and very efficient arithmetic operations on fixed decimal point numbers 
monoidsubclasses
Subclasses of Monoid with a solid theoretical foundation and practical purposes 
eigen
Haskel binding for Eigen library. Eigen is a C++ template library for linear algebra: matrices, vectors, numerical solvers, and related algorithms.
Build timeseriesbased applications quickly and at scale.
* Code Quality Rankings and insights are calculated and provided by Lumnify.
They vary from L1 to L5 with "L5" being the highest.

stats
command line statistics
Feed in statistics on standard input and see number of samples, average, minimum, 1st quartile, median, 3rd quartile and maximum. Input can be prefixed with a common string, only the last word needs to be a number value. Statistics will be computed for each run of lines with equal prefixes.
Some statistics about the byte length of the first 10,000 words in the dictionary:
> head n 10000 /usr/share/dict/words  while read line; do echo $line  wc c; done  stats
Samples: 10000.0
Average: 8.63739999999999
