## Codebook Dissimliarities

### Description

Functions to calculate distances/dissimilarities between codebooks.

### Usage

    hellingerDistance(x,y)
    squaredHellingerDistance(x,y)
    symmetricAlphaDivergence(x,y)

### Arguments

`x` | a codebook
`y` | a codebook

### Details

Note: The symmetric alpha-divergence is proportional to the Squared Hellinger distance, and is the default divergence between codebooks.

### Value

Returns a numeric dissimilarity between two codebooks.
