LRDemo

Intro

Linear regression demo made with C standard & POSIX libs.

Install

Linux/Unix:

Clone:

git clone https://github.com/SuXYIO/LRDemo

Compile:

cd LRDemo
make

Windows:

Not supported yet.
With versions including and after commit 7bbfc08c43ca8c24be9d7da5e21884a420c4fa7a, the program uses POSIX libs, which vanilla Windows doesn't support. The versions before might have a chance of working on Windows.
Might work if using methods like MinGW to use POSIX standards on Windows.

Usage

./LR.out [options]

Args

See manual:

./LR.out -h

Other

1. ./stat/plot.py
   A simple plot python program for plotting the CSV formatted file that can be outputted by LR using -f option (see Args).
   Note that it needs matplotlib and pandas lib to work.
   More info in plot.py's first mutiline comment.
2. ./stat/mutiplot.py
   A version of plot.py, but shows two set of CSV formatted file merged into one plot, doesn't show gradient information.
   More info in mutiplot.py's first mutiline comment.
