The requirements are very minimal, you simply need the latest version of JDK (8.0 or above) installed.
Linux
The first option is to use the command line.
#Update and install JDK8
sudo apt-get update
sudo apt-get install openjdk-8-jdk
#Export PATH/Environment Variables
export JAVA_HOME=/usr/lib/jvm/java-8-openjdk
export PATH=$PATH:/usr/lib/jvm/java-8-openjdk/bin
The second option is to download the appropriate .deb package directly from the Oracle Site
Mac & Windows
Navigate to Oracle Site and download the appropriate package.
JavaStat is a multifunctional statistics library that allows users to carry out basic and advanced statistic calculations on 1D and 2D datasets.
This ranges from simple operations such as the mean & standard deviations to data-modelling operations such as linear regression.
Head over the Releases section of the repository and download the latest stable release of this software.
Probability distributions can be imported using:

The regression analysis can be imported using:

Least Square Regression
Bionomial
The bionomial distribution is modelled by the mathematical equation.
//Returns a single probability value.
public static final double probBionomial(int r, int N, double p)
//Returns a distribution.
public static final double[] distBionomial(int N, double p)Exponential
The exponential distribution is modelled by the mathematical equation.
//Returns P(X=x;lambda)
public static final double probExponential(double lambda, double x)
//Returns P(X=x;lambda) for all x in [0,N]
public static final double[] distExponential(double lambda, int xMax)I welcome any suggestions to how this library can be improved. Please let me know if:
- There's a mistake you find.
- A functionality is missing from the library.
Simply raise an issue in the Issues tab of the project and I will take a look as soon as I can.
