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.
