calculate R^2

[statlearn]

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.

There is a relationship between the three sums of squares. I'm almost certain if you've learned the terms the course has introduced the relationship that you can use to find one of them if you know the other two.

No, it turns out that the formula is this one :

• SST = SSR + SSE
