ParaRMST: Restricted Mean Survival Time

Description

Calculates the RMST as the area under a fitted parametric survival distribution.

Usage

ParaRMST(fit, tau, sig = 0.05)

Value

Data.frame containing the estimated RMST at each truncation time.

Arguments

fit

Fitted parametric survival distribution.

tau

Numeric vector of truncation times.

sig

Significance level, for CIs.

Examples

# Generate Weibull data with 20% censoring.
data <- GenData(n = 1e3, dist = "weibull", theta = c(2, 0.5), p = 0.2)

# Fit Weibull distribution.
fit <- FitParaSurv(data, dist = "weibull")

# Calculate RMSTs.
rmst <- ParaRMST(fit = fit, tau = c(0.5, 1.0, 1.5, 2.0))

# Generate gamma data with 10% censoring.
data <- GenData(n = 1e3, dist = "gamma", theta = c(2, 2), p = 0.10)

# Fit gamma distribution.
fit <- FitParaSurv(data, dist = "gamma")

# Calculate RMSTs.
rmst <- ParaRMST(fit = fit, tau = c(0.5, 1.0, 1.5, 2.0))
