Genome-Wide Association Study Based on Random Regression Model Reveals Candidate Genes Associated with Longitudinal Data in Chinese Simmental Beef Cattle [PDF]
Animals, 2021 Body weight (BW) is an important longitudinal trait that directly described the growth gain of bovine in production. However, previous genome-wide association study (GWAS) mainly focused on the single-record traits, with less attention paid to ...

The Log-Logistic Regression Model Under Random Censoring [PDF]
The Egyptian Statistical Journal, 2006 A regression analysis of the failure time is considered when the failure time is a random censored and has the log-logistic distribution. The regression model has been used to identify the relationship between the failure time and the explanatory ...

Coefficient of Determination for Random Coefficient Regression Model. [PDF]
The Egyptian Statistical Journal, 1998 Random coefficient regression (RCR) model offers an approach by which to take into account nonsystematic changes in the parameters. Swamy (1970,1971) derived estimators of the RCR model parameters.

Downscaling of Regional Air Quality Model Using Gaussian Plume Model and Random Forest Regression
Atmosphere, 2023 High PM10 concentrations are still a significant problem in many parts of the world. In many countries, including Poland, 50 μg/m3 is the permissible threshold for a daily average PM10 concentration.
