GetShape: Life-table Shape Measures

In jschoeley/pash: Pace-Shape Analysis of Life-tables

Description

Get life table shape measures from pace-shape object.

Usage

GetShape(pash, type = "all", harmonized = TRUE)

Arguments

pash	A pace-shape object.
type	Which shape measure should be returned (default "all")?
harmonized	Should the harmonized version of the shape measures be returned (default TRUE)?

Details

If harmonized == TRUE, then all shape measures are re-scaled so that (1) they are positive for monotonically increasing forces of mortality over age (2), they are negative for monotonically decreasing forces of mortality over age, (3) they are 0 for constant forces of mortality over age, (4) they have a maximum value of 1. See Wrycza etal. (2015) for details.

If harmonized == FALSE the shape measures have their conventional scaling.

Value

The following shape measures are reurned:

"entropy"

Life table entropy

"gini"

Life table Gini coefficient

"cv"

Life table coefficient of variation.

"mr"

Mortality Ratio - Wrycza et al. (2015)

"ler"

Life Expectancy Ratio - Wrycza et al. (2015)

"acfm"

Average of Change in Force of Mortality with respect to lx - Wrycza et al. (2015)

"psmad"

Probability to Survive up to the Mean Age at Death - Wrycza et al. (2015)

"all"

All of the above measures.
