| Jun 20, 2013 at 10:20 | comment | added | tiantianchen | I know a more standard way to obtain something similar to model2: introduce a second stratification variable-group and apply the model ($\beta$,$\beta_{group}$) to the total_data. The likelihood ratio test would be to test against H0:$\beta_{group}=0$. Is this the same as the method I described above? | |
| Jun 20, 2013 at 10:19 | comment | added | Glen_b | You still need to resolve the question of what you mean by "maxlog-likelihood" earlier; I suggest making an edit to clarify both parts of your question. | |
| Jun 20, 2013 at 10:17 | comment | added | tiantianchen | Yes, this is what I suppose in this method: the log-likelihoods for the subsets can be added to obtain the overall log-likelihood. I don't know whether this is valid and I need some expert to point out what's the problem with this. | |
| Jun 20, 2013 at 9:40 | comment | added | Glen_b | What is 'maxlog-likelihood'? Is it the maximum of the log-likelihood, or the maximizer of it? Whichever it is, why can you sum them? Do you mean instead that the log-likelihoods for the subsets can be added to obtain the overall log-likelihood, or that the maximum value of the overall log-likelihood must always be the sum of the two maximum values obtained on the subsets? | |
