...ification errors ( alpha and beta) that would be expected as a consequence of sampling clusters (villages / households) instead of usual SRS under traditional LQAS. In order to estimate the classification errors I would like to simulate correlated binary outcomes for a given level of prevalence and intracluster correlation (rho). Specifically I would like simulate an LQAS plan (33 clusters of 6 children each, n =198 children) to generate clusters with specific intercluster (0.05) and intracluster correlation (0.1) subject to the constraint that the intercluster correlation is less than or equal to intr...

Hi, Can R calculate an intraclass correlation coefficient for clustered data, when the outcome variable is dichotomous? By now I calculate it by hand, estimating between- and intracluster variance by one-way ANOVA - however I don't feel very comfortable about this, since the distributional assumptions are not really met.... Maybe anyone can help me? Best regards and many many thanks, Veronique Verhoeven University of Antwerp

Dear all, I have been searching far and wide for a solution to the problem of negative intracluster correlation in the case of a binomial response variable (also known as under-dispersion). Prentice (1986) (http://www.jstor.org/stable/2289219) developed an extension of the beta-binomial model which allowed for this negative correlation.

...Or am I wasting my time trying to get it to > work? > > In oVirt 4.x I was able to do it and also to intermix normal vnic and OVN based vnic. I needed to reproduced a problem I had in a physical Red Hat Cluster. So i "cloned" the physical nodes to oVirt VMs and the vnic of the intracluster network of this virtual RedHat cluster was put on OVN, while the production vnic was on a normal lan. Both with virtio as the network type and the second with openvswitch virtualport. I just simulate it on a RHV 4.3.7 env and it starts ok the snippet of the dynamic xml definition that RHV creates...
