A data frame with 500 rows and 14 columns:

USUBJID: Unique subject identifiers for patients.
ARM: Assigned treatment arm.
AGE: Age in years at baseline.
SEX: Sex of patient recorded as character "Male"/"Female".
SMOKE: Smoking status at baseline as integer 1/0.
ECOG0: Indicator of ECOG score = 0 at baseline as integer 1/0.
N_PR_THER: Number of prior therapies received as integer 1, 2, 3, 4.
SEX_MALE: Indicator of SEX == "Male" as numeric 1/0.
AGE_CENTERED: Age in years at baseline relative to average in aggregate data agd.
AGE_MEDIAN_CENTERED: AGE greater/less than MEDIAN_AGE in agd coded as 1/0 and then centered at 0.5.
AGE_SQUARED_CENTERED: AGE squared and centered with respect to the AGE in agd. The squared age in the aggregate data is derived from the \(E(X^2)\) term in the variance formula.
SEX_MALE_CENTERED: SEX_MALE centered by the proportion of male patients in agd
ECOG0_CENTERED: ECOG0 centered by the proportion of ECOG0 in agd
SMOKE_CENTERED: SMOKE centered by the proportion of SMOKE in agd
N_PR_THER_MEDIAN_CENTERED: N_PR_THER centered by the median in agd.
