In latrend: A Framework for Clustering Longitudinal Data

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

Description

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

Usage

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.

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