Investigation for periodic and almost periodic solutions of first-order ordinary differential equations [PDF]

E3S Web of Conferences, 2023
Approaches to estimating for the number of periodic and almost periodic solutions of ordinary differential equations are considered. Conditions that allow determinating both the upper and lower bounds for these solutions are found.

Household food insecurity and cooking energy access in Nigeria: A panel data approach

Energy Nexus, 2023
Access to sources of cooking energy has potential impacts on food security, however, there is a paucity of information and empirical evidence on their linkages.

Evaluation of Clear-Sky Incoming Radiation Estimating Equations Typically Used in Remote Sensing Evapotranspiration Algorithms

Remote Sensing, 2013
Net radiation is a key component of the energy balance, whose estimation accuracy has an impact on energy flux estimates from satellite data. In typical remote sensing evapotranspiration (ET) algorithms, the outgoing shortwave and longwave components of ...

An epidemiological study of the predictors of multidrug resistance and methicillin resistance among Staphylococcus spp. isolated from canine specimens submitted to a diagnostic laboratory in Tennessee, USA [PDF]

PeerJ, 2023
Background Understanding drivers of multidrug resistance (MDR) and methicillin resistance, which have increased among canine staphylococcal isolates, is essential for guiding antimicrobial use practices.

Iterative estimating equations: Linear convergence and asymptotic properties [PDF]

, 2007
We propose an iterative estimating equations procedure for analysis of longitudinal data. We show that, under very mild conditions, the probability that the procedure converges at an exponential rate tends to one as the sample size increases to infinity.

Solving Estimating Equations With Copulas

Journal of the American Statistical Association, 2023
Thanks to their ability to capture complex dependence structures, copulas are frequently used to glue random variables into a joint model with arbitrary marginal distributions. More recently, they have been applied to solve statistical learning problems such as regression or classification.
