In latrend: A Framework for Clustering Longitudinal Data

Two-step clustering through linear regression modeling and k-means

Description

Two-step clustering through linear regression modeling and k-means

Usage

lcMethodLMKM(
  formula,
  time = getOption("latrend.time"),
  id = getOption("latrend.id"),
  nClusters = 2,
  center = meanNA,
  standardize = scale,
  ...
)

Arguments

formula	A formula specifying the linear trajectory model.
time	The name of the time variable.
id	The name of the trajectory identification variable.
nClusters	The number of clusters to estimate.
center	A function that computes the cluster center based on the original trajectories associated with the respective cluster. By default, the mean is computed.
standardize	A function to standardize the output matrix of the representation step. By default, the output is shifted and rescaled to ensure zero mean and unit variance.
...	Arguments passed to stats::lm. The following external arguments are ignored: x, data, control, centers, trace.
