Create the training data for each of the k models in k-fold cross validation evaluation

createTrainDataFolds(
  data,
  folds = 10L,
  id = getOption("latrend.id"),
  seed = NULL
)

Arguments

data: A data.frame representing the complete dataset.
folds: The number of folds. By default, a 10-fold scheme is used.
id: The trajectory identifier variable.
seed: The seed to use, in order to ensure reproducible fold generation at a later moment.

Value

A list of data.frame of the folds training datasets.

Examples

data(latrendData)
method <- lcMethodLMKM(Y ~ Time, id = "Id", time = "Time")

if (require("caret")) {
  trainFolds <- createTrainDataFolds(latrendData, folds = 5, id = "Id", seed = 1)

  foldModels <- latrendBatch(method, data = trainFolds)
  testDataFolds <- createTestDataFolds(latrendData, trainFolds)
