    calculate R^2

    Is there a formula or a process to calculate R^2 given the SSE and SSR while the SST and the values of each sample remain unknown ? Thank you all in advance.

    how to say if missing more than X?

    hi all, let's say i want to take the average of 5 scores for assignments [X1 X2 X3 X4 X5]. how do i dictate missing if 2 OR MORE scores are missing? so if any 2 or more are missing then it lists average as not available? thank you
