    Experimental Design help

    Been running around in circles with this for a while. I am trying to figure what sort of design I have and how to go about analyzing it. Any help would be great. Details are below. Sample Date, 3 levels, fixed Field, 2 levels, assumed to be random from a larger population. For each sample...

    What is the best way to scale input-output data for regression?

    I took a look around the forum, but couldn't find any examples for preparing data to multivariate regression... What do you think is the best way to scale? Should it be applied to each input and output variable or just the output? Thanks in advance.
