I've read some papers about p* and one paper about p2.
If I've read correctly, Equation 4 of reference 2 ;extends ;first p*
(equation 1) to contain covariates. And p2 is 'the extension of p1 that
doesn't assume dyadic independence and accounts for nodal & dyadic
Does p* (equation 4 in reference 2) contain p2? Because p* has p1 as
submodels, p2's model equation is very similar to p*'s. If not, what is the
unique features of p2?
Thanks in advance for any comments.

alpha_k * d_k(x) + theta' * t(x)) / c(alpha, beta, theta) ; (d_k : the
