getReStruc: Calculate random effect structure

Description

Calculate random effect structure Calculates number of random effects, number of parameters, blocksize 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)
