getReStruc

Calculate random effect structure Calculates number of random effects, number of parameters, block size and number of blocks. Mostly for internal use.

Description

Calculate random effect structure Calculates number of random effects, number of parameters, block size and number of blocks. Mostly for internal use.

Usage

getReStruc(reTrms, ss = NULL)

Arguments

`reTrms`	random-effects terms list
`ss`	a character string indicating a valid covariance structure. Must be one of `names(glmmTMB:::.valid_covstruct)`; default is to use an unstructured variance-covariance matrix (`"us"`) for all blocks).

Value

a list

`blockNumTheta`	number of variance covariance parameters per term
`blockSize`	size (dimension) of one block
`blockReps`	number of times the blocks are repeated (levels)
`covCode`	structure code

Examples

data(sleepstudy, package="lme4")
rt <- lme4::lFormula(Reaction~Days+(1|Subject)+(0+Days|Subject),
                    sleepstudy)$reTrms
rt2 <- lme4::lFormula(Reaction~Days+(Days|Subject),
                    sleepstudy)$reTrms
getReStruc(rt)
