Thread: Regression in Statistics Question

For a multiple regression model, SST = 189, and SSE = 30, then the proportion of the total variation in the observed y’s that is not explained by the model is?

Please show work + answer.

I've tried different formulas such as sst - sse and found a site saying ss/sst

Can someone please help here?

Thanks

You should say what SST and SSE are. Better notation is something like SS(Total) and SS(Error), which is what I'm assuming those two stand for - SST is also sometimes used as SS(Treatments).

I looked at the question and even I'm confused. Wouldn't the unexplained part of the model be SSE? The explained variation of the model is SSR.
