Combine Several Likelihood Functions Multiplicatively
Combine several likelihood functions, so that the new functions gives the product of all likelihoods (the sum of the log likelihoods). This assumes that all likelihoods are independent from one another!
This function is little tested. Use at your own risk!
A list of likelihood functions. All must be of the same type, with the same argnames, and not constrained.
