Also, Do I need to go back and study matrix algebra in detail?

Thank you? What are your experiences?

Thank you? What are your experiences?

one of my math profs (i come from a background in math/stats and then transitoned to gradschool in psychometrics) used to say that one never learns enough calculus and linear algebra. so i would advise you to take it although when if i compare the class i took in multivariate statistics with the math dept as an undergrad with the class i took on multivariate statistics in the psych dept it was like night and day. only basic knowledge of matrix algebra was required for psychology whereas the one in math did ask me to be very proficient in it.

now, with that being said, knowing linear algebra helps you understand everything in a class way beyond from you knowing the basic tricks and rote memory stuff of how to put things in the software and generate output. why is this important? well, it is important because if one of these days you end up with a particular nasty dataset on which you cannot use the usual tricks people use to analyze data then you're out of luck, but if you understand how methods work you'll always be able to modify them to accommodate what you need. so it never hurts to learn something new

Thanks

Fisher himself referred to ANOVA as simply "a convenient method of arranging the arithmetic."
