mel <- ISwR::melanom %>%
mutate(status = case_when(status %in% c(1, 3) ~ 1,
TRUE ~ 0)) %>%
mutate(thick_cat =
case_when(thick <= 129 ~ "less equal 129",
thick <= 322 ~ "less equal 322",
thick > 322 ~ "greater 322")) %>%
mutate(thick_cat = fct_relevel(thick_cat, "≤ 129", "≤ 322")) %>%
mutate(sex = case_when(sex == 2 ~ "male",
sex == 1 ~ "female"),
ulc = case_when(ulc == 1 ~ "present",
ulc == 2 ~ "absent"))
x <- cureit(surv_formula = Surv(days, status) ~ ulc + sex + thick_cat + thick,
cure_formula = ~ ulc + sex, data = mel)
nomogram.cureit(x,time=300)
predict(x,times=c(100,300)
One thing we can further add is to allow the nomogram.cureit
function to take more than one time point, so that survival probabilities at multiple times can be generated on the nomogram.
Look at examples with broom mixture models and gam models.

Greetings, as a medical student, I am greatly intrigued by the mix cure model. The Cureit package, which enriches the smcure function with evaluation metrics and visualization capabilities, is an invaluable R package. However, these evaluations pertain solely to the training set, with no apparent consideration for the test set. I am curious about how to apply the predict function to the mix cure model.
Add a function that calculates K-index (https://academic.oup.com/biostatistics/article/19/1/14/3798781).
{evacure} package has code for this https://github.com/elong0527/evacure
sc
on the nomogramlp
is scaled: what's the theoretical maximum and minimum of lp
? Is it necessary to get the range of lp
from real data?smcure::smcure()
function to save the bootstrap iterations. This will allow us to use these bootstraps to calculate Brier score. (Evacure package has done this already but we may want to keep changes to a minimum: https://github.com/elong0527/evacure/blob/master/R/smcure1.R) - @tengfei-emoryem()
function. Right now you get errors or warnings with bootstraps (example coming soon)- @karissawhitingA certain way of resampling data often causes warning or even an error of the Cox submodel in the cure model. This essentially means the more bootstrap runs we generate, the higher chance of observing a warning or getting an error.
