I am calculating the likelihood of a hierarchical model and am having trouble distributing the product sign.
Here are the two expressions that I'm interested in:
Product from j=1 to j_k of: (t_jk)^(sum(Z_ijk) + a_k - 1)
and
Product from k=1 to K of: (b_k)^(j_k*a_k).
The tricky part for me is distributing the product sign across the base and the exponent terms simultaneously. Is it possible?
