Angles as Probabilities [PDF]

open access: yesThe American Mathematical Monthly, 2009
We use a probabilistic interpretation of solid angles to generalize the well-known fact that the inner angles of a triangle sum to 180 degrees. For the 3-dimensional case, we show that the sum of the solid inner vertex angles of a tetrahedron T, divided by 2*pi, gives the probability that an orthogonal projection of T onto a random 2-plane is a ...

Probability, propensity and probability of propensities (and of probabilities) [PDF]

open access: yesAIP Conference Proceedings, 2017
Invited contribution to the proceedings MaxEnt 2016 based on the talk given at the workshop (Ghent, Belgium, 10-15 July 2016), supplemented by work done within the program Probability and Statistics in Forensic Science at the Isaac Newton Institute for Mathematical Sciences ...

Generalised block bootstrap and its use in meteorology [PDF]

open access: yesAdvances in Statistical Climatology, Meteorology and Oceanography, 2017
In an earlier paper, Rakonczai et al.(2014) emphasised the importance of investigating the effective sample size in case of autocorrelated data. The simulations were based on the block bootstrap methodology.

Leveraging Twitter data to understand public sentiment for the COVID‐19 outbreak in Singapore

open access: yesInternational Journal of Information Management Data Insights, 2021
Microblogging has become one of the most useful tools for sharing everyday life events and news and for expressing opinions about those events. As Twitter posts are short and constantly being generated, they are a great source for providing public ...

Lexicographic probability, conditional probability, and nonstandard probability [PDF]

open access: yesGames and Economic Behavior, 2010
The relationship between Popper spaces (conditional probability spaces that satisfy some regularity conditions), lexicographic probability systems (LPS's), and nonstandard probability spaces (NPS's) is considered. If countable additivity is assumed, Popper spaces and a subclass of LPS's are equivalent; without the assumption of countable additivity ...

Mathematical Framework for Mixed Reservation- and Priority-Based Traffic Coexistence in 5G NR Systems

open access: yesMathematics, 2023
Fifth-generation (5G) New Radio (NR) systems are expected to support multiple traffic classes including enhanced mobile broadband (eMBB), ultra-reliable low-latency communications (URLLC), and massive machine-type communications (mMTC) at the same air ...

Combining Non-Probability and Probability Survey Samples Through Mass Imputation [PDF]

open access: yes, 2021
Analysis of non-probability survey samples requires auxiliary information at the population level. Such information may also be obtained from an existing probability survey sample from the same finite population. Mass imputation has been used in practice

The quantum probability ranking principle for information retrieval [PDF]

open access: yes, 2009
While the Probability Ranking Principle for Information Retrieval provides the basis for formal models, it makes a very strong assumption regarding the dependence between documents.

Circular functional analysis of OCT data for precise identification of structural phenotypes in the eye

open access: yesScientific Reports, 2021
Progressive optic neuropathies such as glaucoma are major causes of blindness globally. Multiple sources of subjectivity and analytical challenges are often encountered by clinicians in the process of early diagnosis and clinical management of these ...

Branching Random Walks with One Particle Generation Center and Possible Absorption at Every Point

open access: yesMathematics, 2023
We consider a new model of a branching random walk on a multidimensional lattice with continuous time and one source of particle reproduction and death, as well as an infinite number of sources in which, in addition to the walk, only the absorption of ...
