Determination of point estimates of negative binomial distribution parameters

open access: yesVojnotehnički Glasnik, 1999
A method for determining point estimates of c and p parameters of the negative binomial distribution has been presented in the paper. This is a method of moments because the estimation of these parameters is based on the mean value m and the standard ...

MARCO+ Tumor‐Associated Macrophages Impede CD8+ T Cell Immunity to Facilitate Immunotherapy Resistance in Renal Cell Carcinoma

open access: yesAdvanced Science, EarlyView.
MARCO+ TAMs dominate restrained cytotoxicity of CD8+ CTLs and ICB resistance in RCC. Mechanically, MARCO impairs MHC‐I‐mediated neoantigen cross‐presentation via the SOCS1‐JAK1‐STAT1‐NLRC5 signaling cascade in TAMs. Targeted MARCO treatment boosts macrophage antigen cross‐presentation and empowers CD8+ T cells, thereby potentiating ICB efficacy ...

Tailored Ordering Enables High‐Capacity Cathode Materials

open access: yesAdvanced Energy Materials, EarlyView.
A comprehensive first‐principles database is constructed to investigate ordering stability and tendencies in rocksalt‐type LiMO2, aiming to tailor both long‐ and short‐range orderings to encourage favorable rocksalt phase stability and Li diffusion in novel cathode design.

INSURANCE RISK CLASSIFICATION WITH NEGATIVE BINOMIAL DISTRIBUTION

open access: yesStatistika, 2014
Risk classification is the process of statistical modeling that classifies risks into cross-classified classes, characterized by the rating factors. In this paper, risk classification is applied to estimate claim frequency rates, expressed in terms of ...

Phase transition and information cascade in a voting model

open access: yes, 2010
We introduce a voting model that is similar to a Keynesian beauty contest and analyze it from a mathematical point of view. There are two types of voters-copycat and independent-and two candidates. Our voting model is a binomial distribution (independent

The effects of agricultural machinery services and land fragmentation on farmers' straw returning behavior

open access: yesAgribusiness, EarlyView.
Abstract Straw returning is important for rural ecological management and sustainable agricultural development. Using farm survey data for Anhui Province, China, in 2020, we applied the double‐hurdle model to investigate the impact of agricultural machinery services and land fragmentation on farmers' straw‐returning behavior, and to explore the ...

Supply chain risk in grain trading: Inventories as real options for shipping grain

open access: yesAgribusiness, EarlyView.
Abstract Integrating trading and logistics is an important challenge in commodity trading. Trading and logistics are strategic decisions and are integral to most commodities including grain shipping by rail, in addition to other modes (barges, ocean shipping). There are substantial risks, such as the ordering and placement of rail cars.
