How do I carry out multivariate analysis using my variable data and mass spectra data in Matlab?

"multivariate" doesn't really narrow it down vary much.

There are many functions in the Statistics Toolbox that may help you. (Do you have that toolbox?) http://www.mathworks.com/products/statistics/

The mvregress() function is one of the simpler ones to set up and use, but that doesn't mean it is the right type of analysis to solve your problem.

There are examples in the documentation.

Hi cyclist, many thanks for your answer.

I am not sure if I have the toolbox as its an institution copy. How do I find out? Sorry for the really obvious question.

I just have to see if any of my clinical variables have a significant effect in terms of the mass spec data

thanks so much

If you type

in the command window, you will see your version and which toolboxes are installed.
