Conditional density for Tx

fx.Rd

Computes \(f_x(t)=f_0(x+t)/S_0(x)\).

Usage

fx(t, x, model, ...)

Arguments

t

Numeric vector of durations (\(t \ge 0\)).

x

Numeric vector of ages (\(x \ge 0\)).

model

One of "uniform", "exponential", "gompertz", "makeham", "weibull".

...

Model parameters:

  • uniform: omega

  • exponential: lambda

  • gompertz: B, c

  • makeham: A, B, c

  • weibull: shape, scale

Value

Numeric vector of densities (\(\ge 0\)).

Details

Vectorization rule: - If t and x are the same length, values are computed elementwise. - If one of t or x has length 1, it is recycled to match the other.
