survival_function_GM: Calculate Gompertz-Makeham Force of Motion

In m-g-h/mortality:

Description

\loadmathjax

Calculates \mjseqnS(t) = -At - \fracR\alpha (\exp(\alpha t) - 1)

Usage

survival_function_GM(t, A, R, alpha)

Arguments

t	numeric scalar or vector corresponding to the age(s) \mjseqnt
A	numeric scalar corresponding to the \mjseqnA parameter
R	numeric scalar corresponding to the \mjseqnR parameter
alpha	numeric scalar corresponding to the \mjseqn\alpha parameter

Value

Returns a numeric scalar giving the Gompertz-Makeham survival probability \mjseqnS(t)

Examples

# You can use a single age:
survival_function_GM(t = 0,
                     A = 0.00033,
                     R = 0.00014,
                     alpha = 0.11521)

# Or a vector of ages:
survival_function_GM(t = 0:100,
                     A = 0.00033,
                     R = 0.00014,
                     alpha = 0.11521)
