Jun 24, 2015 at 20:57 | comment | added | Torvon | Thank you. In a minor analysis of a paper, we want to establish whether the 6 networks estimated via Ising Models differ (same variables, but different samples). This is extremely demanding and worth at least a PhD project, so not feasible for this paper. So we look for simpler ways. One idea we had was determine the variability of each edge across the 6 networks, and if this variability is substantial, that provides some information. I could bootstrap confidence interval around each edge in each network. That would provide information about error. Would that help? | |
Jun 24, 2015 at 16:04 | comment | added | whuber♦ | Assuming no measurement error, if the observed variance is nonzero, then it is significantly above zero (at any possible level of significance), because it definitively establishes the variance is nonzero. If there is a possibility of measurement error, then what quantitative information can you provide about its variance? This is such a strange situation that it makes one wonder whether you are asking the question you need to. Could you clarify what you really mean by "significant variability across the ... networks in [an] edge"? | |
