Here's some help:
Also check out the sum() and sqrt() functions. To square, use the caret:
term1 = sum(O) ^ 2
Multiplication is * and division is /. Not hard. Just take it one term at a time:
term1 = ....
term2 = ....
denominator = ....
rSquared = ( (term1 - term2 * term3) / denominator) ^2
Or you can simply use the built in functions for mse() and corrcoef().

Sure we can help you but all you gave was a partial snippet of one of your attempts, which was just a partial snippet of my answer above:
function [term1 , term2] = stat(o , t)
term1=...
term2=...
end
It seems you forgot to upload your entire two code attempts so how can I comment on them? So I guess my answer stands as-is until you upload your code. Come on, you can do it, you're a smart engineer. It sounds like homework, and if so I'm sure your instructor didn't just say "See if someone in the Answers forum can do your homework problem for you."
