After my meeting a few things: Grant and MM paper deadlines are 1/31. Once these things are off my plate, I can focus on other things for my thesis. For the next 20 days, see if I can model something … Continue reading
Deadlines!!! December 21, 2011 – Mailing draft of MMSBM paper! January 6, 2011 – AERA invited IES student poster: Submit a 1-2 description of my work (MMSBM stuff) January 15, 2011 – RAND Summer Internship Refine CV and cover letter … Continue reading
I can talk about some results….that I might be able to add to the paper. I have this sticky issue of the theta’s moving to the edges of my simplex, yet the other papers I’ve read have results where the … Continue reading
There are many and I have a feeling it will prove necessary to have them all in one place. December 15, 2011 – the JSM paper competition. Just need Brian to sign his letter, scan it and email the following: … Continue reading
Goals: (1) Start coding a simple HMMSBM where the Dirichlet hyperparameters are estimated and come from the same distribution whose hyperparameters are also estimated. We will hold \xi fixed to be 1/g for now, and try to do just estimate … Continue reading
Lots of goals, but lots of progress! Ask Brian about writing me a letter for a JSM travel award. stud12an MMSBM – I coded the single network sampler to estimate the Dirichlet hyperparameter and so far things look okay. ***Found … Continue reading
On my To Do list from Wednesday. (1) Find a network clustering algorithm. Ask Andrew for one. Update: Using Mclust instead, but I have to deal with a warning b/c of the dimensionality:data ratio. Uses BIC to choose clusters which … Continue reading
(1) Find a network clustering algorithm. Ask Andrew for one. (2) Incorporate rho into the MCMC by using the estimate in the Ado paper. Not the MLE, but the “dumb” estimate. (3) Run clustering algorithm on original Y, newY from … Continue reading
Things never seem to work out when you need them to. /sigh My log posterior traceplots are not working out. For some reason my log posterior traceplots (data set 1) are converging to each other (even though the individual parameter … Continue reading
So it seems a stronger prior for the entries of the B matrix is needed when either the network is larger or there are more groups. Recall for 3 groups, I used a uniform prior and things looked fine. Test … Continue reading
