Statistics for Swift — v0.1.4

A custom implementation of GitHub site with the purpose of streamlining access to built-in functions and classes. This is starting out as a personal project to facilitate the authors needs and intersts.

Features

Base Functions

• factorial
• choose (nCk)
• median
• mean
• variance
• standardDeviation
• erfinv (erf part of Foundation)
• lsr, least squares regression

Discrete Distributions

• Bernoulli
• Poisson
• Geometric
• Binomial
• CustomDiscrete (new)

Continuous Distributions

• Normal
• Log-normal
• Laplace
• Weibull (new)
• Exponential
• CustomRanked (new, needs pdf implementation)

And each distribution has these methods:

• pmf or pdf
• cdf
• quantile
• random (takes an optional int and returns an array of that length, or otherwise a single value)

Testing

Run swift test from the base directory in a terminal window.
