In NetSimR: Actuarial Functions for Non-Life Insurance Modelling

The probability density function (pdf) of a Sliced LogNormal Pareto severity distribution

Description

Gives the probability density at the claim amount x of a sliced severity distribution, with LogNormal attritional claims below the slice point and a Pareto tail above it.

Usage

dSlicedLNormPareto(x, mu, sigma, SlicePoint, shape)

Arguments

x	A real number - the claim amount where the probability density function (pdf) will be evaluated. The pdf is 0 for negative x.
mu	A real number - the first parameter of the attritional Claim Severity's LogNormal distribution.
sigma	A positive real number - the second parameter of the attritional Claim Severity's LogNormal distribution.
SlicePoint	A positive real number - the slice point and the scale parameter of the Claim Severity's Pareto distribution. An infinite slice point gives the LogNormal distribution.
shape	A positive real number - the shape parameter of the Claim Severity's Pareto distribution.

Details

shape is the Pareto shape parameter, usually written alpha; the sliced Gamma-Pareto functions call the same parameter PShape.

Value

The value of the probability density function (pdf) at x with an attritional claim LogNormal distribution with parameters mu and sigma and a large claim Pareto distribution with parameters SlicePoint and shape. A non-numeric argument or a non-positive sigma, SlicePoint or shape is an error; NA values give NA.
