glmmTMB (version 0.2.3)

getReStruc: Calculate random effect structure Calculates number of random effects, number of parameters, blocksize and number of blocks. Mostly for internal use.

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

# NOT RUN {
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)
# }
