It would benefit from some rewriting -- smaller paragraphs and grammar checking..
Re Grey box completion and validation
“See also“ “Grey box completion and validation“ has been removed anonymously without explanation from this and several other topics. Following advice from Wikipedia if there are no objections (please provide your name and reasons), I plan to reinstate the reference in a weeks time.
The removed reference provides additional information on types of non linear models and techniques for using them. In particular most models are incomplete (i.e. a grey box) and thus need completion and validation. This reference seems to be within the appropriate content of the “See also” section see Wikipedia:Manual_of_Style/Layout#See_also_section.
