daprpr: Data Preprocessing

In crmReg: Cellwise Robust M-Regression and SPADIMO

Data Preprocessing

Description

Data preprocessing, classical and robust centering and scaling.

Usage

daprpr(Data, center.type, scale.type)

Arguments

Data	the data.
center.type	type of centering as R function name (e.g. "mean", "median", "l1median").
scale.type	type of scaling as R function name (e.g. "sd", "qn", "Sn", "scaleTau2").

Details

daprpr preprocesses the data by classical or robust centering and scaling. Given center.type = "mean" and scale.type = "sd", function daprpr is equivalent to scale(Data, center = TRUE, scale = TRUE).

Value

daprpr returns the scaled data with attributes "Center", "Scale" and "Type".
