| Symmetric, Long-Tailed Histogram |

| Description of Long-Tailed |
The above is a histogram of
the DZIUBA1.DAT data set.
The previous example contains a discussion of the distinction between short-tailed, moderate-tailed, and long-tailed distributions. In terms of tail length, the histogram shown above would be characteristic of a "long-tailed" distribution. |
||
| Recommended Next Step | If the histogram indicates a symmetric, long tailed distribution, the recommended next step is to do a Cauchy probability plot. If the Cauchy probability plot is linear, then the Cauchy distribution is an appropriate model for the data. Alternatively, a Tukey Lambda PPCC plot may provide insight into a suitable distributional model for the data. | ||
