Chemometrics Software

Aside

To do chemometrics, you could choose to either build your own software/worksheet or use third-party software. In this post I will tell you about some pros and cons of widely used software and the function requirements.

Techniques used in chemometrics include:

  • Linear Regression (linreg)
  • Non-Linear Regression (polynomial and exponential)
  • Principal components Analysis (PCA)
  • Partial least squares scores (PLS)
  • Experimental design (factorial design)
  • Multivariate Analysis

The software I looked at is expensive, but with cheaper student versions available.

  • Minitab
  • SPSS
  • SAS

For both SPSS and SAS you need extra`s. While there is only one version of Minitab.

Linux Kernel 3.0.0 release candidate 1 installation guide for Ubuntu Linux

Aside

This short walkthrough describes how to get the latest linux kernel working under Ubuntu Linux without having to compile it yourself.

This tutorial should work with the latest version of Ubuntu Linux (10.04 LTS, 10.10, 11.04 and 11.10) and most distributions based on these versions of Ubuntu Linux like Mint.

The included kernel files have been compiled using the generic ubuntu configuration.
Note: ATI, Intel and NVIDIA drivers are automatically installed using DKMS, if you have these installed and up-to-date. Else … don`t blaim me.

For a difference, this guide is only for the AMD64 platform.

Installation Guide

  1. Download the kernel headers package;

    linux-headers-3.0.0-0300rc1_3.0.0-0300rc1.201105310830_all.deb
  2. And the appropriate package for your system

    linux-headers-3.0.0-0300rc1-generic_3.0.0-0300rc1.201105310830_amd64.deb
  3. And the accompanying compiled kernel;

    linux-image-3.0.0-0300rc1-generic_3.0.0-0300rc1.201105310830_amd64.deb
  4. Install the files in the same order (else it won`t work!)
  5. In the terminal run:

    sudo update-grub
  6. Reboot and select the kernel from the bootloader menu

    If it`s not there check all steps (and of course for errors)
