For Problem, evaluate the linear multiple regression model with two or three predictor variables. Compute the multiple correlation coefficient, the standard error of estimate, and the standard deviation of the variable y. Discuss the reliability of the model.
Let y1 x1, and x2 be the peak discharge (qp in ft3/sec), drainage area (A in acres), and the rainfall intensity (i in in./hr), respectively:
qp | 23 | 45 | 44 | 64 | 68 | 62 |
I | 3.2 | 4.6 | 5.1 | 3.8 | 6.1 | 7.4 |
A | 12 | 21 | 18 | 32 | 24 | 16 |
