Simulated datasets for demonstration

Description

The dataset was generated based on the proposed model h(t; \boldsymbol{Z}_i, {X}_i(\cdot))=h_{0}(t-t_{i,j-1}) \exp \left(\eta_{ij}\right), where h_0(\cdot) is the baseline hazard function generated from a Weibull distribution. \eta_{ij} = \bm{\alpha}^{\top}\boldsymbol{Z}_i +\int_{t_{i, j-1}}^{t}{X}_{i}(s)\beta(s)ds + v_{ij}. \bm{\alpha} is the fixed effect parameter associated with the time-invariant covariates \boldsymbol{Z}_i, and \beta(t) is a time-varying coefficient that captures the effect of functional predictor X_{i}(t) on the hazard rate of recurrent events. The simulated dataset is organized into two data frames: a survival data frame (sdat) and a functional data frame (fdat). The variables in each data frame are listed below:

Usage

data(simDat)

Format

A list with two data frame:

sdat

Survival data; a data frame with xxx rows and xxx variables:

id

Subjects identification

event

A sequence of the number of events per subject

t_start

Event starting time

t_end

Event end time

censoring_time

Event censoring time

status

Event status: status=1 if event is observed and status=0 if event is censored

z1

A univariate scalar covariates. Can be extended to multiple scalar covariates

fdat

Functional data; a data frame with xxx rows and xxx variables:

id

Subjects identification

time

Time points for each longitudinal measurement

x

Longitudinal measurements at distinct time points
