Simple question: how is RMSE calculated?
Hello, when plotting a simple regression graph I can get the R^2 and RMSE.I would like to know how is RMSE calculated specifically in JMP.This is because I read somewhere (Fearn 2002) that some people take the square root of the squared sum of error, devided by n while others devided by n-1. How does JMP 13 Pro do it? Thanks!
