sigmaThetaExpr_viewer

Knowing the difficulty of visualizing the covariance structure, especially when the user chooses to determine his own structure. This function was developed,that allows the user to view the provided structure even before it is evaluated, that is, through mathematics symbolic.

Matching longitudinal methodology models with complex sampling design. It fits fixed
and random effects models and covariance structured models so far. It also
provides tools to perform statistical tests considering these specifications as described in : Pacheco, P. H. (2021). "Modeling complex longitudinal data in R: development of a statistical package." <https://repositorio.ufjf.br/jspui/bitstream/ufjf/13437/1/pedrohenriquedemesquitapacheco.pdf>.
