UpdateAlpha function

Update the Dirichlet process concentration parameter.

Using the procedure outlined in West (1992) we sample the concentration parameter of the Dirichlet process. See reference for further details.

UpdateAlpha(dpobj)

## Default S3 method:
UpdateAlpha(dpobj)

## S3 method for class 'hierarchical'
UpdateAlpha(dpobj)

Arguments

• dpobj: Dirichlet process object.

Returns

A Dirichlet process object with updated concentration parameter.
