## Central Concentration for Nominal Variables
This vignette demonstrates how to compute the central concentration for nominal variables using the `central_concentration` function from the `nomiShape` package. Central concentration quantifies how concentrated the distribution of a nominal variable is around its most frequent categories.

### Computing Central Concentration

```{r central-concentration-example-1}
# Example usage of central_concentration
central_concentration(categories, "animal")
```

```{r central-concentration-example-2}
# Example usage of central_concentration
central_concentration(categories2, "animal")
```

```{r central-concentration-example-3}
# Example usage of central_concentration
central_concentration(categories3, "animal")
```
