  Hello, I have some questions.  When I have a linear model in JMP, I want to force intercept to zero.So, In Fit Special,  I chose "Constrain Intercept to 0" then I got the new output from JMP. My questions are1) why JMP does not provide R-squared when intercept becomes zero? 2) R-squared is calculated by SSR/SST, can I calculate R-squared by myself using the data JMP provides?
