Stixbox Overview

A statistics toolbox.

Description

Stixbox is a statistics toolbox which provides distribution functions, datasets, statistical tests and plotting facilities.

It is compatible with the french examination "agregation de mathematiques".

It depends on the "apifun" module.

Quick Start

In the following example, we plot the probability distribution function (PDF) of the Normal (Laplace-Gauss) law in the interval [-5,5].

x = -5:0.1:5 ;
y = dnorm(x);
scf();
plot(x,y);

In the following example, we generate random variables from the Normal distribution function and plot the associated histogram.

x=rnorm(1000,0,1);
scf();
[y,e]=histo(x);

This module provides a collection of 23 datasets. In the following script, we extract the data for the dataset #10.

[x,txt] = getdata(10)
