Tyche build scala version

Tyche is a small and robust statistical library for the JVM. Many JVM-hosted numerical libraries offer similar functionalities, but they seem to be unnecessarily bloated and they fail to provide straightforward APIs. Instead, Tyche is built from the ground up in accordance to good design principles.

  • Discrete & Continuous distributions.
  • Foolproof analysis tools.
  • Markov chains and lattice walks.
  • Simple Random Sampling (SRS) support.
  • Extensive documentation and good test coverage.

The library is written in Scala 2.12.0 and was tested last with sbt 0.13.13.

Behold, the power of Tyche:

// In a country in which people only want boys every family continues to
// have children until they have a boy. If they have a girl, they have
// another child. If they have a boy, they stop. What is the average
// amount of kids per family?

sealed trait Child
object Boy extends Child
object Girl extends Child

val family = tyche.DiscreteDistribution.uniform(Boy, Girl)
  .until(_ contains Boy)

println(family.mean) // ~ 2.0


Tyche is published to Maven Central, so you just need to paste this line in you build configuration file:

libraryDependencies += "com.github.neysofu" %% "tyche" % "0.4.3"
