Which is the best estimate of the residual value when x = 1?

-1

-0.5

0.5

1.5

The best estimate of the residual value when x = 1 is 1.5 (5-3.5). The Residual value is a difference between the measured value and the predicted value of a regression analysis. The graphic show the diagonal line as the predicted value, therefore if x = 1, the predicted value would be 3.5 and the point shows the measured value which is 5.

Idon’t understand what you’re asking..

Ya i could just need to know what type of math
