Standard Error Estimate for Robust Location (Mean) M-Estimator of Returns

Description

robMean.SE computes the standard error of the robust location (mean) M-estimator of the returns.

Usage

robMean.SE(
  data,
  family = c("mopt", "opt", "bisquare")[1],
  eff = 0.95,
  se.method = c("IFiid", "IFcor", "IFcorAdapt", "IFcorPW", "BOOTiid", "BOOTcor")[c(1, 4)],
  cleanOutliers = FALSE,
  fitting.method = c("Exponential", "Gamma")[1],
  d.GLM.EN = 5,
  freq.include = c("All", "Decimate", "Truncate")[1],
  freq.par = 0.5,
  corOut = c("none", "retCor", "retIFCor", "retIFCorPW")[1],
  return.coef = FALSE,
  ...
)

Arguments

data	Data of returns for one or multiple assets or portfolios.
family	Family for robust m-estimator of location. Must be one of "mopt" (default), "opt" or "bisquare".
eff	Tuning parameter for the normal distribution efficiency. Default is 0.99.
se.method	A character string indicating which method should be used to compute the standard error of the estimated standard deviation. One or a combination of: "IFiid" (default), "IFcor", "IFcorPW", "IFcorAdapt" (default), "BOOTiid" or "BOOTcor".
cleanOutliers	Boolean variable to indicate whether the pre-whitenning of the influence functions TS should be done through a robust filter. Default if FALSE.
fitting.method	Distribution used in the standard errors computation. Should be one of "Exponential" (default) or "Gamma".
d.GLM.EN	Order of the polynomial for the Exponential or Gamma fitting. Default polynomial order of 5.
freq.include	Frequency domain inclusion criteria. Must be one of "All" (default), "Decimate" or "Truncate."
freq.par	Percentage of the frequency used if "freq.include" is "Decimate" or "Truncate." Default is 0.5.
corOut	Return correlation of the returns or the influence function transformed returns. Must be one of "retCor", "retIFCor" or "none" (default).
return.coef	Boolean variable to indicate whether the coefficients of the penalized GLM fit are returned. Default if FALSE.
...	Additional parameters.

Value

A vector or a list depending on se.method.
