Enhancing water use efficiency in precision irrigation: data-driven approaches for addressing data gaps in time series

Frontiers in Water, 2023
Real-time soil matric potential measurements for determining potato production's water availability are currently used in precision irrigation. It is well known that managing irrigation based on soil matric potential (SMP) helps increase water use ...

Comparing Methods to Select Candidates for Re-Genotyping to Impute Higher-Density Genotype Data in a Japanese Black Cattle Population: A Case Study

Animals, 2023
As optimization methods to identify the best animals for dense genotyping to construct a reference population for genotype imputation, the MCA and MCG methods, which use the pedigree-based additive genetic relationship matrix (A matrix) and the genomic ...

Genotype Imputation to Improve the Cost-Efficiency of Genomic Selection in Rabbits

Animals, 2021
Genomic selection uses genetic marker information to predict genomic breeding values (gEBVs), and can be a suitable tool for selecting low-hereditability traits such as litter size in rabbits.

Design of an imputation methodology by random selection using regression trees

Bulletin of Computational Applied Mathematics, 2021
One of the biggest issues in the information collection stage is the absence of data, this research focuses specifically on the scenario when the loss is partial, completely random and the data is quantitative. There are classic techniques to impute data,

Comparison of different imputation methods from low- to high-density panels using Chinese Holstein cattle

Animal, 2013
Imputation of high-density genotypes from low- or medium-density platforms is a promising way to enhance the efficiency of whole-genome selection programs at low cost.

Multiple imputation of missing covariates with non-linear effects and interactions: an evaluation of statistical methods. [PDF]

, 2012
BACKGROUND: Multiple imputation is often used for missing data. When a model contains as covariates more than one function of a variable, it is not obvious how best to impute missing values in these covariates.
