The present paper studies hypothesis testing of graphs in this high-dimensional regime, where the goal is to test between two populations of inhomogeneous random graphs defined on the same set of n vertices. The size of each population m is much smaller than n, and can even be a constant ...

In this article, we consider a semiparametric problem of two-sample hypothesis testing for a class of latent position random graphs. We formulate a notion of consistency in this context and propose a valid test for the hypothesis that two finite-dimensional random dot product graphs on a common...
Performing Two Sample Test for VariancesTo perform a two-sample test for variances: Select Statistics: Hypothesis Testing: Two-Sample Test for Variances. This opens the TwoSampleTestVar dialog box. Specify the Input Data Form (Indexed or Raw) and then fill Input Data, the F-test for ...
