Lactation-wide genetic insights into nitrogen utilization in grazing dairy cows

Journal of Dairy Science
: Societal and economic pressure to reduce nitrogen use in the dairy cow sector is increasing. One potential contributing solution is to breed more nitrogen-efficient dairy cows that excrete less nitrogen.

Exponential-family Random Network Models

, 2012
Random graphs, where the connections between nodes are considered random variables, have wide applicability in the social sciences. Exponential-family Random Graph Models (ERGM) have shown themselves to be a useful class of models for representing com ...

Random regression analyses using B-splines to model growth of Australian Angus cattle

Genetics Selection Evolution, 2005
Regression on the basis function of B-splines has been advocated as an alternative to orthogonal polynomials in random regression analyses. Basic theory of splines in mixed model analyses is reviewed, and estimates from analyses of weights of Australian ...

A novel analysis of random forest regression model for wind speed forecasting

Cogent Engineering
This article uses a random forest regression (RFR) model to analyze wind speed forecasting. Wind energy is one of the more critical potentials in renewable energy sources for producing a clean and safe environment. Accurate and stable wind forecasting is
