 2. **Calculate the Dispersion Statistic**:
    - For **Poisson regression**, the dispersion statistic is calculated as:
 
-   $$
-   \text{Dispersion} = \frac{\sum_{i=1}^{n} (y_i - \hat{y}_i)^2 / \hat{y}_i}{n - p}
-   $$
+ $$
+ \text{Dispersion} = \frac{\sum_{i=1}^{n} (y_i - \hat{y}_i)^2 / \hat{y}_i}{n - p}
+ $$
 
    Where:
    - $y_i$ is the observed value.
