extractStruct function

Extracting models' structures

Functions extracting the structure of the models under both hypothesis: the number of fixed and random effects, the number of tested fixed and random effects, and the residual dimension, as well as the random effects covariance structure

extractStruct(m1, m0, randm0)

Arguments

• m1: the model under H1
• m0: the model under H0
• randm0: a boolean stating whether the model under H0 contains any random effect

Returns

A list with the following components: - detailStruct: a data frame containing the list of the parameters and whether they are tested or not

• nameVarTested: the name of the variance components being tested

• nameFixedTested: the name of the fixed effects being tested

• dims: a list with the dimensions of fixed and random effects, tested or not tested

• structGamma: the structure of the covariance matrix of the random effects diag, full or blockDiag
