In a simple regression model, if Σ(ŷ-ȳ)² and r²=0.75, then the value of SST is equal to: a. 80 b. 75 c. 102 d. 100
Added by Brandon P.
Step 1
In a simple regression model, if Ʃ(ŷ-ȳ)2 and r2=0.75 then the value of SST is equal to: We know that SST (total sum of squares) is equal to the sum of the squared deviations of the actual values from the mean. In other words, SST = Ʃ(y-ȳ)2. However, we are Show more…
