From distrEx v0.4-2 by Matthias Kohl

Generic function for the computation of clipped second moments

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

Keywords: methods, distribution

Usage

m2df(object, upper)

Arguments

object: object of class "Distribution"
upper: clipping bound

Details

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

Value

The second moment of object clipped at upper is computed.

concept

moment

Examples

# standard normal distribution
N1 <- Norm()
m2df(N1, 0)

# Poisson distribution
P1 <- Pois(lambda=2)
m2df(P1, 3)

# absolutely continuous distribution
D1 <- Norm() + Exp() # convolution
m2df(D1, 2)
m2df(D1, Inf)
E(D1, function(x){x^2})
