In statistics, the reduced chi-square statistic is used extensively in goodness of fit testing. It is also known as mean squared weighted deviation (MSWD) in isotopic dating[1] and variance of unit weight in the context of weighted least squares.[2][3]
Its square root is called regression standard error,[4] standard error of the regression,[5][6] or standard error of the equation[7] (see Ordinary least squares § Reduced chi-squared)
