I am a graduate student in imaging genetics. When I have a statistics questions and search online and can often find answers. However, I cannot cite User Generated Content. Can you suggest some reference books contain all the formulas for all the formulas of common statistics methods?
For example, I have recently read an answer about the formula for calculating SE of predictor variable (x). But I cannot find the formula in books like Handbook of Regression Analysis (I can only see formula of SE of y).
