**Regression Analysis Output**

**Model Equation:**  
\( Y = aX^bZ^cT^d \)

The following table presents the computer output from estimating the parameters of the nonlinear regression model:

| **Observations:** | 32 |
|-------------------|----|
| **Dependent Variable:** | LNY |
| **R-Square:** | 0.7766 |
| **F-Ratio:** | 32.44 |
| **P-Value on F:** | 0.0001 |

| **Variable** | **Parameter Estimate** | **Standard Error** | **T-Ratio** | **P-Value** |
|--------------|------------------------|--------------------|-------------|-------------|
| Intercept    | -0.6931                | 0.32               | -2.17       | 0.0390      |
| LNR          | 4.66                   | 1.36               | 3.43        | 0.0019      |
| LNS          | -0.44                  | 0.24               | -1.83       | 0.0774      |
| LNT          | 8.28                   | 4.60               | 1.80        | 0.0826      |

**Based on the information in the table, the estimated value of \( a \) is:**

**Multiple Choice:**

- -0.6931 (selected)
- 0.50
- -3.67
- 2.66

**Analysis:**

The table shows key statistics for a nonlinear regression model including parameter estimates for the intercept and variables LNR, LNS, and LNT. The R-square value indicates that approximately 77.66% of the variability in the dependent variable \( LNY \) is explained by the model. Each parameter estimate is listed along with its standard error, T-ratio, and P-value to evaluate statistical significance, with a focus on whether each coefficient significantly differs from zero.
