My article presents four general kinds of model-based graphical diagnostics: 1. Displays of raw data, with a model used to simulate the reference distribution of the displays (as in Figure 1). Conversely, Figure 2 illustrates the difficulty, in general, of interpreting data displays without a comparison to a reference distribution. 2. Similar displays of tests of lower-dimensional data summarie...

Normal lymphocytes from the peripheral circulation represent a heterogenous population of cells with different surface markers and different functions. Some of these lymphocytes contain cytoplasmic inclusions called parallel tubular arrays (PTA). which can only be identified with certainty under the electron microscope. It is not known whether this ultrastructurally defined lymphocyte constitut...

When doing stochastic modeling one often face the problem of sampling from a posterior pdf on the form const l p where the normalizing constant is unknown The corresponding likelihood function l tends to be complicated and computational expensive while the prior p tends to be simpler This work origin from stochastic reservoir charac terization and history matching where calculation of the likel...

Blacklegged ticks (n=12,606) were collected over four years (2007-2010) as part of a national passive tick surveillance program conducted in Canada by the National Microbiology Laboratory (NML) using the methods described previously (1). Adult I. scapularis were also collected by drag sampling: in 2008 from Itasca State Park, Camp Ripley and St. Croix State Park (n=56 per locality) in Minnesota...

My views on the semantic and pragmatic interpretation of natural language were influenced a lot by the works of Martin, Jeroen and Frank. What attracted me most is that although their work is always linguistically relevant, it still has a philosophical point to make. As a student (not in Amsterdam), I was already inspired a lot by their work on dynamics semantics, and by Veltman’s work on data ...

Why do we build models? There are two basic reasons: explanation or prediction [Ripley, 2004]. Using large ensembles of models for prediction is commonplace, but is rarely used for explanation, where we typically choose one “best” model. When there are several equally good models, it is common sense to look at them too, but can the “bad” models tell us something as well? This paper describes ex...

This package vignette is designed as a hands-on tutorial for estimating temporal exponential random graph models (TERGMs) (Desmarais and Cranmer 2010, 2012b; Hanneke et al. 2010) and assessing goodness of fit and predictive performance (Cranmer and Desmarais 2011; Leifeld and Cranmer 2014) using the xergm package (Leifeld et al. 2014) for the statistical computing environment R (R Core Team 201...

While action potentials are the usual means of transmission in axons, recent work has established that decrementally conducted potentials are also utilized. Decremental conduction has been demonstrated to be the exclusive mode of transmission in certain sensory axons of vertebrates (Werblin & Dowling, 1969; Kaneko, 1967, 1970) and invertebrates (Gwilliam, 1965, Ripley, Bush & Roberts, 1968; Ioa...
