plusmin {elect}

Computation of a function of life expectancies

Description

Compute an additive function of a series of estimated life expectancies

Usage

plusmin(x, index = NA, func = "plus", probs = c(0.025, 0.5, 0.975), digits = 3)

Arguments

x

Life expectancies estimated by elect

index

Selection of the life expectancies in the function (following the order in summary)

func

Required series of "plus" and "minus". Example: func = c("plus","plus")

probs

Probabilities for the quantiles

digits

Number of digits in the output

Details

This function requires that uncertainty of LEs is estimated; that is, S is not 0.

Examples

# Fit msm model:
Q     <- rbind(c(0,0.01,0.01), c(0,0,0.01), c(0,0,0))
model <- msm(state~age, subject = id, data = electData,
             center = FALSE, qmatrix = Q, deathexact = TRUE,
             covariates = ~age+x)

# Estimate function of life expectancies:
sddata <- electData[electData$bsline == 1,]
LEs    <- elect(x = model, b.covariates = list(age = 0, x = 1),
                statedistdata = sddata, h = 0.5, age.max = 50, S = 25)
plusmin(LEs, index = c(2,4), func = "plus")
