Re-interpreting conventional interval estimates taking into account bias and extra-variation

open access: yesBMC Medical Research Methodology, 2006
Background The study design with the smallest bias for causal inference is a perfect randomized clinical trial. Since this design is often not feasible in epidemiologic studies, an important challenge is to model bias properly and take random and ...

An interval compositional vehicular traffic model for real-time applications [PDF]

open access: yes, 2008
This paper proposes an interval approach to vehicular traffic flow modeling. The developed interval compositional model (ICM) provides a natural way of predicting traffic flows without the assumption of uniform distribution of vehicles along the road ...

Quantile estimates of entropy uncertainty for distributions supported on bounded interval [PDF]

open access: yesITM Web of Conferences
Formulas for calculating the Shannon information entropy and the entropy uncertainty interval are obtained, which are based on calculating quantile estimates of random variable distributions and are set over a limited range of random variable values ...

Confidence interval based parameter estimation--a new SOCR applet and activity. [PDF]

open access: yesPLoS ONE, 2011
Many scientific investigations depend on obtaining data-driven, accurate, robust and computationally-tractable parameter estimates. In the face of unavoidable intrinsic variability, there are different algorithmic approaches, prior assumptions and ...

Modeling circadian and sleep-homeostatic effects on short-term interval timing [PDF]

open access: yes, 2015
Short-term interval timing i.e., perception and action relating to durations in the seconds range, has been suggested to display time-of-day as well as wake dependent fluctuations due to circadian and sleep-homeostatic changes to the rate at which an ...

Dynamics of non-classical interval exchanges [PDF]

open access: yes, 2010
A natural generalization of interval exchange maps are linear involutions, first introduced by Danthony and Nogueira [Measured foliations on non-orientable surfaces. Ann. Sci. Éc. Norm. Supér. (4) 26(6) (1993), 645–664].
