Compute Functional Trimmed Variance — trimvar • fdars

Computes the trimmed variance by excluding curves with lowest depth.

Usage

trimvar(
  fdataobj,
  trim = 0.1,
  method = c("FM", "mode", "RP", "RT", "BD", "MBD", "FSD", "KFSD", "RPD"),
  ...
)

Arguments

fdataobj: An object of class 'fdata'.
trim: Proportion of curves to trim (default 0.1).
method: Depth method to use. One of "FM", "mode", "RP", "RT", "BD", "MBD", "FSD", "KFSD", or "RPD". Default is "FM".
...: Additional arguments passed to the depth function.

Value

An fdata object containing the trimmed variance function.

Examples

fd <- fdata(matrix(rnorm(100), 10, 10))
tv <- trimvar(fd, trim = 0.2)
tv_mode <- trimvar(fd, trim = 0.2, method = "mode")
