m2df

From distrEx v1.9 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
functional
truncated 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})
