An Extension of the Quadratic Error Function for Learning Imprecise Data in Multivariate Nonlinear Regression

open access: yesJournal of Probability and Statistics, 2020
Multivariate noises in the learning process are most of the time supposed to follow a standard multivariate normal distribution. This hypothesis does not often hold in many real-world situations.

Causal analysis of trade loss from pathogens: A global study of foot and mouth disease impacts on meat exports

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract Our general interest is in global trade loss from livestock pathogens, specifically exports. We adopt a causal inference approach that considers animal disease outbreaks over time as non‐staggered binary treatments with the potential for switching in (infection) and out of treatment (recovery) within the sample period. The outcome evolution of

Nonparametric Predictive Inference for Ordinal Data and Accuracy of Diagnostic Tests [PDF]

open access: yes, 2012
This thesis considers Nonparametric Predictive Inference (NPI) for ordinal data and accuracy of diagnostic tests. We introduce NPI for ordinal data, which are categor- ical data with an ordering of the categories.

Seeds of change: The impact of Ethiopia's direct seed marketing approach on smallholders' seed purchases and productivity

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract While multiple factors explain low adoption rates of improved varieties by small‐scale farmers in sub‐Saharan Africa, a key supply‐side constraint is the limited availability of seed embodying new traits in the volume, quality, price, and timeliness required by farmers. This constraint is partly attributable to classical failures in the market

Data generation and application using the neutrosophic Erlang distribution

open access: yesJournal of Big Data
The Erlang distribution in classical statistics has traditionally been used for reliability analysis when there is no uncertainty in the underlying data. However, this classical framework cannot be applied in environments with inherent uncertainty.

Comparison of different classifiers with varying amounts of imprecise data.

open access: yes, 2019
This table compares the performance of different classifiers for the original MIMIC II data and a version of the MIMIC II data where 50% of observations were randomly perturbed by a value ϵ, distributed normally with mean zero and the empirical variance ...

Cumulative Antigen Suppression Reduces Clonal Plasma Cell Evolution in Gaucher Disease

open access: yesAmerican Journal of Hematology, EarlyView.
ABSTRACT Chronic antigenic stimulation is implicated in the pathogenesis of monoclonal gammopathy and multiple myeloma, yet longitudinal human evidence linking sustained antigen exposure to modifiable clonal plasma cell evolution remains limited. Gaucher disease (GD), caused by biallelic GBA1 pathogenic variants, is characterized by accumulation of ...
