A set of formulae have been collated with brief explanation for each pertaining to a statistical method called Test of Hypothesis from a very few set of sources. I would like to publish this work on ResearchGate. But what will I call it? It is neither research paper of novel method nor a standard survey paper. I don't suppose this is a technical report either. Yet I do believe this material would be helpful to many. What may I publish this as?
My comment turned into answer: you could call it an "expository paper", especially if it contains some more descriptive details on how/where to use/apply these formulas.
At least in my field (mathematics) such papers are not unheard of. These are often published in journals more aimed towards such papers with a broader audience, for example the American Mathematical Monthly or Expositiones Mathematicae. These papers can be of great value as a clear and easy reference to results in a particular field; on the other hand, they may not quite be considered research papers.
