linearest

Determination of maximum technical efficiency (MTE) and plateau regression.

Performs analyzes and estimates of environmental covariates
and genetic parameters related to selection strategies and development
of superior genotypes. It has two main functionalities, the first being
about prediction models of covariates and environmental processes, while
the second deals with the estimation of genetic parameters and selection
strategies. Designed for researchers and professionals in genetics and
environmental sciences, the package combines statistical methods
for modeling and data analysis. This includes the plastochron estimate
proposed by Porta et al. (2024) <doi:10.1590/1807-1929/agriambi.v28n10e278299>,
