Description

Generic function for the computation of clipped second moments. The moments are clipped at upper.

Usage

m2df(object, upper)

Arguments

object

object of class "Distribution"

upper

clipping bound

Value

• The second moment of object clipped at upper is computed.

concept

• moment
• functional
• truncated moment

Details

The precision of the computations can be controlled via certain global options; cf. distrExOptions.
