WebLinking the hierarchical structure works in the same way as with PyMC nodes, however, note that here we pass in our newly create Knode to mu. Note moreover that while we say that this node depends on the data column 'subj_idx' (this column is supposed to have all the subject indices), we don't have to specify again that this child node also depends on …
