Abstract
Recent years have seen a growing array of activities in developing statistical models for modelling real-life networks. Since many of these networks are sparse, an all too often practice in the literature is to apply a developed model to a sub-network typically by discarding nodes due to their lack of connectivity. In this note, we provide the first result highlighting issues with this practice which we call the fallacy of data-selective inference. We demonstrate this fallacy by examining the estimation bias in the Erd˝os-Rényi model theoretically and in the stochastic block model empirically.
