Data & Statistics
| Parameter | Negative Binomial | Zero Inflated Negative Binomial |
|---|---|---|
| Mean | r * p / (1 – p) | (r * p) / (1 – p) * (1 – w) + w * r |
| Variance | r * p / (1 – p)^2 | (r * p) / (1 – p)^2 * (1 – w) + w * r * (1 – w) |
Expert Tips
- Always ensure your data is count data with excess zeros.
- Be cautious when interpreting results, as the inflation parameter can significantly impact the distribution.
Interactive FAQ
What is the difference between Negative Binomial and Zero Inflated Negative Binomial distributions?
The main difference is the presence of an inflation parameter (w) in the zero inflated version, which allows for excess zeros in the data.
