UpdateAlpha function

Update the Dirichlet process concentration parameter.

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.
