Advanced Data Analysis from an Elementary Point of View (2017) [pdf]
`This book does not presume that you
once learned but have forgotten the material from the pre-requisites; it presumes that
you know that material and can go beyond it. The book also presumes a firm grasp
on linear algebra and multivariable calculus, and that you can read and write simple
functions in R. If you are lacking in any of these areas, now would be an excellent
time to leave.`<p>ouch.
