The **Box-Cox transformation** doesn’t directly [handle](https://www.mindstick.com/articles/311004/suede-skillet-handle-cover) negative data. However, there’s a modified version of it for negative values. Here’s how it works:

**Negative Data**:

- For negative data, we use a modified formula:

f(x)=λ(x+c)λ−1​

- where **c** is a constant added to make the data positive.
- We choose **λ** to optimize normality.

Remember, the goal is to make our data more normally distributed.
