rc9.fund: Fundamental Parameters for Rogers-Castro Migration Schedule

Description

Set of fundamental parameters suggested by Rogers and Castro (1981).

Usage

data(rc9.fund)

Details

A list of the parameters required by the rc9 function: $$a_{1} = 0.02$$ $$\alpha_{1} = 0.1$$ $$a_{2} = 0.06$$ $$\alpha_{2} = 0.1$$ $$\mu_{2} = 20$$ $$\lambda_{2} = 0.4$$ $$c = 0.003$$ Can be copied and altered to illustrate the effect of parameters.

Examples

# check format
str(rc9.fund)

# single age groups
x <- 1:100

plot(x, rc9(x, rc9.fund), type="l")

# alter to see the effect of mu2
p1 <- rc9.fund
p1$mu2 <- 30
plot(x, rc9(x, rc9.fund), type="l")
