Restricted mean survival time as a function of restriction time
(BirkhäuserWiley Periodicals, Inc., 2022-03)
Restricted mean survival time (RMST) is a clinically interpretable and meaningful survival metric that has gained popularity in recent years. Several methods are available for regression modeling of RMST, most based on ...
Statistical inference for association studies using electronic health records: handling both selection bias and outcome misclassification
(Wiley Periodicals, Inc., 2022-03)
Health research using electronic health records (EHR) has gained popularity, but misclassification of EHR‐derived disease status and lack of representativeness of the study sample can result in substantial bias in effect ...
Investigating preservice teachers’ assessment skills: Relating aspects of teacher noticing and content knowledge for assessing student thinking in written work
(Wiley Periodicals, Inc.Jossey Bass, 2022-03)
This mixed methods study explored the development of elementary and middle school preservice teachers’ (PSTs) learning to assess student thinking through analysis of students’ written work. Six sections of the first ...
Asymptotics for small nonlinear price impact: A PDE approach to the multidimensional case
(Cambridge University PressWiley Periodicals, Inc., 2021-01)
We provide an asymptotic expansion of the value function of a multidimensional utility maximization problem from consumption with small nonlinear price impact. In our model, cross‐impacts between assets are allowed. In the ...
MLMC method to estimate propagation of uncertainties in electromagnetic fields scattered from objects of uncertain shapes
(Wiley‐VCH GmbH, 2021-01)
We estimate the propagation of uncertainties in electromagnetic wave scattering problems. The computational domain is a dielectric object with uncertain shape. Since classical Monte Carlo (MC) method is too expensive, we ...
Double ramification cycles with target varieties
(BirkhäuserWiley Periodicals, Inc., 2020-12)
Let X be a nonsingular projective algebraic variety over C, and let M¯g,n,β(X) be the moduli space of stable mapsf:(C,x1,…,xn)→Xfrom genus g, n‐pointed curves C to X of degree β. Let S be a line bundle on X. Let A=(a1,⋯,an) ...
Non‐integrality of some Steinberg modules
(BirkhäuserWiley Periodicals, Inc., 2020-06)
We prove that the Steinberg module of the special linear group of a quadratic imaginary number ring which is not Euclidean is not generated by integral apartment classes. Assuming the generalized Riemann hypothesis, this ...
Structural factor equation models for causal network construction via directed acyclic mixed graphs
(Wiley Periodicals, Inc.Pearson Prentice Hall, 2021-06)
Directed acyclic mixed graphs (DAMGs) provide a useful representation of network topology with both directed and undirected edges subject to the restriction of no directed cycles in the graph. This graphical framework may ...
Asymptotics of the k‐free diffraction measure via discretisation
(Cambridge University PressWiley Periodicals, Inc., 2021-06)
We determine the diffraction intensity of the k‐free integers near the origin.
Estimating and inferring the maximum degree of stimulus‐locked time‐varying brain connectivity networks
(Wiley Periodicals, Inc.Cambridge University Press, 2021-06)
Neuroscientists have enjoyed much success in understanding brain functions by constructing brain connectivity networks using data collected under highly controlled experimental settings. However, these experimental settings ...
