## Dominance Index for Nominal Variables

This vignette demonstrates how to compute the dominance index for nominal variables using the `dominance_index` function from the `nomiShape` package. The dominance index quantifies the degree to which a few categories dominate the distribution of a nominal variable.

### Computing Dominance Index

    # Example usage of dominance_index
    dominance_index(categories, "animal")
    #> [1] 0.091712

    # Example usage of dominance_index
    dominance_index(categories2, "animal")
    #> [1] 0.113056

    # Example usage of dominance_index
    dominance_index(categories3, "animal")
    #> [1] 0.295584
