Maximum Likelihood
I have got to the second equation down, where it has the pipe and the product sign. At the end there is the format $(x_i; \theta_1, \theta_2 ..._k, \theta_3)$. What does the ; mean? The product of all x with all theta? (i.e. $(x_1\theta_1, x_2\theta_2)$, etc.)
If so, you know x, but you don't know theta. I assume this is what you have to estimate by maximising L or $\Lambda$. If so, what is Lambda?
