R Documentation

Convert from continuous to useful variables for TopCut Model

Description

Convert from continuous to useful variables for TopCut Model

Usage

db.topcut(db, zcut, tcut, name = db.getname(db, "z", 1),
          radix = "Topcut", modify.target = db.locmod())

Arguments

db	The db-class where the continuous variable must be translated
zcut	Cutoff value
tcut	Mean of the variable above the cutoff
name	Name of the variable of interest. By default, this is set to the first z-locator variable.
radix	Radix of the name given to the variables storing the results in the target Db.
modify.target	Decides whether or not the newly created variables will have their locator defined or not. For more information, see db.locmod.

Value

The db-class structure contains the result of this function. These new variables are:

• The variable truncated below the cutoff value: Zc = pmin(Z, zcut)

• The Indicator of the variable above the cutoff: Ind = Z >= zcut

• The Residual above the cutoff: R = Z - Zc - (tcut - zcut) * Ind
