Description
Simulated dataset to illustrate the use of WCE models
Usage
data(drugdata)
Format
A data frame with 77038 rows and 7 variables for 500 individuals. The data frame is formatted in an interval format.
- Id
numeric vector to identify observations that belong to the same individual.
- Event
numeric vector representing the event of interest. Takes the value of 1 in the interval during which the event occurs and is 0 otherwise.
- Start
numeric vector indicating the beginning of the interval.
- Stop
numeric vector indicating the end of the interval.
- sex
numeric vector indicating males (0) and females (1).
- age
numeric vector representing age at baseline.
- dose
numeric vector representing time-dependent doses of a drug.
Details
The variables sex and age are covariates. They are optional and illustrate the inclusion of adjustment variables. Covariates can be numeric or factors.
Source
This dataset was simulated using the PermAlgo package (https://cran.r-project.org/package=PermAlgo).
