Evaluation of survival extrapolation in immuno-oncology using multiple pre-planned data cuts: learnings to aid in model selection

open access: yesBMC Medical Research Methodology, 2020
Background Due to limited duration of follow up in clinical trials of cancer treatments, estimates of lifetime survival benefits are typically derived using statistical extrapolation methods.

On the Sequential Hierarchical Cognitive Diagnostic Model

open access: yesFrontiers in Psychology, 2020
Model data fit plays an important role in any statistical analysis, and the primary goal is to detect the preferred model based on certain criteria. Under the cognitive diagnostic assessment (CDA) framework, a family of sequential cognitive diagnostic ...

Remarks on drift estimation for diffusion processes [PDF]

open access: yes, 2009
In applications such as molecular dynamics it is of interest to fit Smoluchowski and Langevin equations to data. Practitioners often achieve this by a variety of seemingly ad hoc procedures such as fitting to the empirical measure generated by the data,

The inert doublet model in the light of Fermi-LAT gamma-ray data: a global fit analysis

open access: yesEuropean Physical Journal C: Particles and Fields, 2017
We perform a global fit within the inert doublet model taking into account experimental observables from colliders, direct and indirect dark matter searches and theoretical constraints.

Comparing Bayesian spatial models: Goodness-of-smoothing criteria for assessing under- and over-smoothing.

open access: yesPLoS ONE, 2020
BACKGROUND:Many methods of spatial smoothing have been developed, for both point data as well as areal data. In Bayesian spatial models, this is achieved by purposefully designed prior(s) or smoothing functions which smooth estimates towards a local or ...

A simulation-based scaled test statistic for assessing model-data fit in least-squares unrestricted factor-analysis solutions

open access: yesMethodology, 2023
A shortcoming of least-squares unrestricted factor analysis (UFA) procedures, which are widely used in psychometric applications is that a test statistic for assessing model-data fit cannot be easily derived from the minimum fit function value. This paper proposes a chi-square type goodness-of-fit test statistic intended for the principal-axis, MINRES,
