lifecontingencies (version 0.0.3)

pxt: Function to evaluate survival, death probabilities and deaths.

Description

These functions evalutate survival and raw death probabilities between age x and x+t

Usage

dxt(object, x, t)

pxt(object, x, t, fractional = "linear")

qxt(object, x, t, fractional = "linear")

Arguments

object

A lifetable object.

x

Age of life X.

t

Period until which the age shall be evaluated. Default value is 1

fractional

Assumptions for fractional age. One of "linear", "hyperbolic", "constant force".

Value

• A numeric value

Warning

The function is provided as is, without any warranty regarding the accuracy of calculations. The author disclaims any liability for eventual losses arising from direct or indirect use of this software.

Details

Fractional assumptions are: -linear: linear interpolation between consecutive ages. -constant force of mortality: constant force of mortality. -hyperbolic: Balducci assumptions. See reference book for details.
