Interrelation of the concept of “uncertainty” in the information theory and theory of measurements
MATEC Web of Conferences, 2017 The problem of determining the optimal number of multiple measurements based on the type of the error distribution density of the measuring means is considered. The laws of distribution of a random variable are obtained, they ensure the extreme values of

Education and completed fertility in Norway [PDF]
Using Norwegian data we find that married women’s education is positively associated with completed fertility, but this relationship becomes insignificant after controlling for husbands’ characteristics. Husbands’ education has a positive effect on women’

Environmental Sciences Europe, 2018 Species reproduction is an important determinant of population dynamics. As such, this is an important parameter in environmental risk assessment. The closure principle computational approach test (CPCAT) was recently proposed as a method to derive a ...

StatsIn real-life inter-related time series, the counting responses of different entities are commonly influenced by some time-dependent covariates, while the individual counting series may exhibit different levels of mutual over- or under-dispersion or mixed

Dispersion Behavior of Coarse Particles by Lateral Vibration under Microgravity [Translated]†
KONA Powder and Particle Journal, 2014 We studied coarse particle behavior in a laterally vibrated vessel under microgravity. Vibration conditions were a frequency of 75-150 Hz and a displacement amplitude of 86-310 μm. The two dimensional displacement

Uncertainty about children's survival and fertility : a test using Indian microdata [PDF]
The authors present a non-altruistic model of demand for children, in the presence of uncertainty about children's survival. Children are seen as assets, as they provide help during old age.

Conwey-Maxwell Poisson Distribution: Approach for Over- and-Under-Dispersed Count Data Modelling
IOP Conference Series: Earth and Environmental Science, 2018 The standard method of count data modeling is Poisson distribution, which has the assumption of equidispersion, as identified by the same mean and variance values. The modelling of count data frequently causes the emergence of over-dispersion which has a higher variance than mean itself.

Sorting, Incentives and Risk Preferences: Evidence from a Field Experiment [PDF]
The, often observed, positive correlation between incentive intensity and risk has been explained in two ways: the presence of transaction costs as determinants of contracts and the sorting of risk-tolerant individuals into firms using high-intensity ...
