Decorate masked data with series system lifetime and right-censoring

Takes component failure times and adds system failure time and right-censoring indicators.

Usage

md_series_lifetime_right_censoring(
  md,
  tau,
  compvar = "t",
  sysvar = "t",
  deltavar = "delta",
  failvar = "k"
)

Arguments

md

Data frame with component failure times (columns t1, t2, ..., tm).

tau

Right-censoring times. Can be scalar or vector of length n.

compvar

Column prefix for component lifetimes. Default is "t".

sysvar

Column name for system lifetime. Default is "t".

deltavar

Column name for censoring indicator. Default is "delta".

failvar

Column name for failed component index. Default is "k".

Value

Modified data frame with additional columns:

• System lifetime (sysvar)

• Censoring indicator (deltavar): TRUE if censored

• Failed component index (failvar)
