Format

A list of the parameters required by the rc9 function: $$ a_{1} = 0.02 $$ $$ \alpha_{1} = 0.1 $$ $$ a_{2} = 0.06 $$ $$ \alpha_{2} = 0.1 $$ $$ \mu_{2} = 20 $$ $$ \lambda_{2} = 0.4 $$ $$ c = 0.003 $$

Examples

# NOT RUN {
# check format
str(rc9.fund)

# single age groups
x <- 1:100
m <- rc9(x, param = rc9.fund)
plot(x, m, type="l")

# alter to see the effect of mu2
p1 <- rc9.fund
p1$mu2 <- 30
m1 <- rc9(x, param = p1)
plot(x, m, type="l")
lines(x, m1, lty=2)
# }
