Variable Selection for data reduction and discriminant anlaysis
Hello all,
I'm dealing with geochemical analyses of some rocks.
If I use the full composition (31 elements or variables), I can get
reasonable separation of my 6 sources. Then when I go onto do LDA with the
6 groups, I get excellent separation.
I feel like I should be reducing the variables to thos that are providing
the most discrimination between the groups as this is important
