latrendBoot: Cluster longitudinal data using bootstrapping

In latrend: A Framework for Clustering Longitudinal Data

Cluster longitudinal data using bootstrapping

Description

Performs bootstrapping, generating samples from the given data at the id level, fitting a lcModel to each sample.

Usage

latrendBoot(
  method,
  data,
  samples = 50,
  seed = NULL,
  parallel = FALSE,
  errorHandling = "stop",
  envir = NULL,
  verbose = getOption("latrend.verbose")
)

Arguments

method	An lcMethod object specifying the longitudinal cluster method to apply, or the name (as character) of the lcMethod subclass to instantiate.
data	A data.frame.
samples	The number of bootstrap samples to evaluate.
seed	The seed to use. Optional.
parallel	Whether to enable parallel evaluation. See latrend-parallel. Method evaluation and dataset transformation is done on the calling thread.
errorHandling	Whether to "stop" on an error, or to ⁠"remove'⁠ evaluations that raised an error.
envir	The environment in which to evaluate the method arguments via compose(). If the data argument is of type call then this environment is also used to evaluate the data argument.
verbose	The level of verbosity. Either an object of class Verbose (see R.utils::Verbose for details), a logical indicating whether to show basic computation information, a numeric indicating the verbosity level (see R.utils::Verbose), or one of c('info', 'fine', 'finest').

Value

A lcModels object of length samples.

Examples

data(latrendData)
method <- lcMethodLMKM(Y ~ Time, id = "Id", time = "Time")
bootModels <- latrendBoot(method, latrendData, samples = 10)

bootMAE <- metric(bootModels, name = "MAE")
mean(bootMAE)
sd(bootMAE)
