 # Arguments
 - `model::AbstractTuringLatentModel`: The latent model to be repeated.
+- `link::Function`: The link function to transform the latent model _before_ broadcasting
+to periodic weekly. Default is `x -> 7 * softmax(x)` which implements constraint
+of the sum week effects to be 7.
 
 # Returns
 - `BroadcastLatentModel`: The broadcast latent model.
