Simulate Data with Optional Blocking
simulate_data.RdThis function generates a simulated dataset containing subject-level data. Users can optionally specify block sizes to generate multiple samples per subject.
Arguments
- n_samples
Integer; the total number of samples to generate. When
block_size> 1, this must be a multiple ofblock_size.- block_size
Integer; the number of samples per subject. If 1 or NULL (default), generates one sample per subject. If > 1, generates multiple samples per subject.
- seed
Integer; the seed for random number generation to ensure reproducibility.
Value
A data.frame with the following structure:
sample_id: Unique identifier for each sampleage_at_baseline: Subject's age at baseline (normally distributed, mean=55, sd=10)bmi_at_baseline: Subject's BMI at baseline (normally distributed, mean=30, sd=5)sex: Subject's sex ("M" or "F")sample_timepoint: Timepoint identifier (only present whenblock_size> 1)treatment: Treatment assignment ("treatment" or "placebo")subject_id: Subject identifier
Details
When block_size is greater than 1, the function generates multiple samples per subject, creating a sample_timepoint column with labels "timepoint_1", "timepoint_2", etc. Subject-level characteristics (age, BMI, sex, treatment) remain constant across all samples for the same subject.
