Footnotes
1
Before the availability of high speed computers, pattern rotation used to be done visually, which made it somehow subjective because of the lack of a quantitative measure and the possibility of non-reproducibility of results.
 
2
An exception is with weighted EOFs, see Sect. 4.2.3
 
3
The reader should note the use of adjectives “simple” and “simplified” to describe other different techniques in the literature.
