Chemometrics Software

Aside

Reply

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.

Inkscape 0.48 Illustrator’s Cookbook review

Posted on by
2

As the title might suggest, this book is a cookbook about Inkscape version 0.48 written for illustrators. This book is published by Packt Publishing and falls in the categories: open-source, graphics, illustration, SVG and is one of Packt’s cookbook series.

As a fellow Inkscape-newbie and Scalable Vector Graphics (SVG) enthusiast I will be reviewing this book.

What`s the book about?

Inkscape is an open source vector graphics editor with features comparable to expensive software like  Adobe Illustrator, Fireworks and ColorDraw. Inkscape uses the W3C Scalable Vector Graphics file format. SVG can also be used on webpages and is fully incorporated into HTML 5 and is therefore a drawing technology of the near-future.

Inkscape can be downloaded from inkscape.org 

Who is this book written for?

This book is written for people without experience with vector graphics design software and can also be used for people new to vector graphics (while moving away from Photoshop) and people who want to learn Inkscape.

This book is also for the intermediate users who want to improve their toolkit and increase their workflow.

To use this book you have to have Inkscape 0.48 installed as well as a text editor with programming functions. An installed version of Python is also recommended but not necessary.

Windows users could also use PortableApps.com version of Inkscape.

Bye Bye Kor deck, hello collection

As announced today, 20June 2011 the following two cards are banned from standard:

  • Jace, the Mind Sculptor
  • Stoneforge Mystic

The rule will be effective from 1 July 2011.

For me it has a plus and a downside:

  • Plus: these cards will be cheaper, I want one  Jace and three Stoneforges to complete my collection
  • Down: Stoneforge Mystic will be lacking from my full-Kor deck.
