The following regression equation was computed from a sample of 20 observations:

Y' = 15 - 5X

SSE was found to be 100 and SS total 400.

a) Determine the standard error of estimate.

b) Determine the coefficient of determination.

c) Determine the coefficient of correlation.

Solution Preview

a) SSE=100
Degree of freedom = 20-2=18
Standard Error = (SSE/degree of ...
