In christophergandrud/SurvSetup: Finds Spell Features that are Useful for Estimating Survival Models

SurvSetup

Finds features of spells that are useful for estimating survival models.

Examples

library(SurvSetup)

# Create fake data ----------------------------------------------
group_id <- c(rep('aa', 7), rep('bb', 4))
x <- c(rep('a', 4), rep('b', 3), 'c', rep('a', 2), 'c')
fake_data <- data.frame(group_id = group_id, spell = x)

head(fake_data)

# Find spell features -------------------------------------------

## Non-grouped data
spell_features(fake_data, var = 'spell')

## Grouped data
spell_features(fake_data, var = 'spell', group = 'group_id')


## Last observation treated as an event (e.g. not right-censored)
spell_features(fake_data, var = 'spell', group = 'group_id',
               right_censored = FALSE)
