Testing homogeneity in Weibull-regression models
(Biometrical Journal, 2022)
Random regression models using Legendre polynomials or linear splines for test-day milk yield of dairy Gyr (Bos indicus) cattle
(2013-01-01)
Studies investigating the use of random regression models for genetic evaluation of milk production in Zebu cattle are scarce. In this study, 59,744 test-day milk yield records from 7,810 first lactations of purebred dairy ...

Estimates of genetic parameters for scrotal circumference using random regression models in Nelore cattle
(Elsevier B.V., 2011-05-01)
A total of 15,901 scrotal circumference (SC) records from 5300 Nelore bulls, ranging from 229 to 560 days of age, were used with the objective of estimating (co)variance functions for SC, using random regression models. ...

Estimation of genetic parameters for milk yield using a random regression test-day model in first parity dairy cows under pasture-based systems of Los Ríos region in Chile
(Universidad Austral de Chile, 2020)
In dairy cattle, genetic selection for milk yield was generally based on 305 days lactation records that were calculated from available monthly test-day milk yield records. A test-day milk yield record, multiplied by the ...
Genetic parameters for body weight in buffaloes (Bubalus bubalis) in Colombia using random regression models
(Elsevier B.V., 2013-12-01)
The objective of this research was to estimate (co) variance functions and genetic parameters for body weight in Colombian buffalo populations using random regression models with Legendre polynomials. Data consisted of ...
