createDatasetsFromList {robustlmm}

Create Dataset List From List of Data Objects

Description

Convert a list of datasets to a dataset list similar to the ones created by generateAnovaDatasets and generateMixedEffectDatasets.

Usage

createDatasetsFromList(
  datasetList,
  formula,
  trueBeta,
  trueSigma,
  trueTheta,
  ...
)

Arguments

datasetList

list of data objects, usually of type data.frame.

formula

formula to fit the model using lmer.

trueBeta

scalar or vector with the true values of the fixed effects coefficients. Can be of length one in which case it will be replicated to the required length if needed.

trueSigma

scalar with the true value of the error scale.

trueTheta

scalar or vector with the true values for the variance component coefficients, not including sigma. Can be of length one in which case it will be replicated to the required length if needed.

...

all additional arguments are added to the returned list.

Details

The returned list can be passed to processFit and to any of the fitDatasets functions. Splitting and binding of datasets using splitDatasets and bindDatasets is not supported.

Value

list that can be passed to processFit and to any of the fitDatasets functions. Only generateData is implemented, all the other functions return an error if called.

Examples

  data(sleepstudy)
  sleepstudy2 <- sleepstudy
  sleepstudy2[1, "Reaction"] <- sleepstudy2[1, "Reaction"] + 10
  fm1 <- lmer(Reaction ~ Days + (Days|Subject), sleepstudy)
  datasets <- createDatasetsFromList(list(sleepstudy, sleepstudy2),
                                     formula = Reaction ~ Days + (Days|Subject),
                                     trueBeta = getME(fm1, "beta"),
                                     trueSigma = sigma(fm1),
                                     trueTheta = getME(fm1, "theta"))
  fitDatasets_lmer(datasets)
