Description Usage Format References Examples

A simulated dataset with time-varying longitudinal outcome, time-to-event, and time-varying covariates. The dataset is already converted into left-truncated right-censored (LTRC) format, so that the Cox model with time-varying longitudinal outcome as a covariate can be fit. See, for example, Fu and Simonoff (2017).

A data frame with 866 rows and 11 variables. The variables are as follows:

- ID
subject identifier (1 - 500)

- X1
continuous covariate between 0 and 1; time-varying

- X2
continuous covariate between 0 and 1; time-varying

- X3
binary covariate; time-varying

- X4
continuous covariate between 0 and 1; time-varying

- X5
categorical covariate taking values from 1, 2, 3, 4, 5; time-varying

- time_L
left-truncated time

- time_Y
right-censored time

- delta
censoring indicator, 1 if censored and 0 otherwise

- y
longitudinal outcome; time-varying

- g
true latent class identifier 1, 2, 3, 4, which is determined by the outcomes of

*1\{X1 > 0.5\}*and*1\{X2 > 0.5\}*, with some noise
