mac.expression {bayesPop}

Expression Generator

Description

Help functions to easily generate commonly used expressions.

Usage

mac.expression(country)
mac.expression1(country)
mac.expression5(country)

Arguments

country

Country code as defined for expressions.

Details

mac.expression and mac.expression1 generate expressions for the mean age of childbearing of the given country, for 5-year age groups and 1-year age groups, respectively. mac.expression5 is a synonym for mac.expression. Note that pop.predict has to be run with keep.vital.events=TRUE for this to work.

Value

mac.expression returns a character string corresponding to the formula (17.5*R_c(15-19) + 22.5*R_c(20-24) + ... + 47.5*R_c(45-49))/100 where R_c(x) denotes the country-specific percent age-specific fertility for the age group x.

mac.expression1 returns a character string corresponding to the formula (10.5*R_c(10-11) + 11.5*R_c(11-12) + ... + 54.5*R_c(54-55))/100

# Run pop.predict with storing vital events
pred <- pop.predict(countries=c("Germany", "France"), nr.traj=3, 
           keep.vital.events=TRUE, output.dir=sim.dir)
# plot the mean age of childbearing 
pop.trajectories.plot(pred, expression=mac.expression("FR"), cex.main = 0.7)
