spdg: Simulated Prognanediol-glucuronid (PDG) Data
In cpr: Control Polygon Reduction

Description Usage Format Details Author(s) Source References

A Simulated data set based on the Study of Women's Health Across the Nation (SWAN) Daily Hormone Study (DHS).

spdg

a data.frame, carries the tbl_df and tbl classes from dplyr. Variables in the data set:

id: Subject ID
age: Age, in years of the subject
ttm: Time-to-menopause, in years
ethnicity: Ethnicity, a factor with five levels: Caucasian, Black, Chinese, Hispanic, and Japanese
bmi: Body Mass Index
day_from_dlt: A integer value for the number of days from Day of Luteal Transition (DLT). The DLT is day_from_dlt == 0. Negative values indicate the follicular phase, positive values for the luteal phase.
day_of_cycle: the day of cycle
day: A scaled day-of-cycle between [-1, 1] with 0 for the DLT. See Details
pdg: A simulated PDG value

Prognanediol-glucuronid (PDG) is the urine metabolite of progesterone. This data set was simulated to have similar characteristics to a subset of the SWAN DHS data. The SWAN DHS data was the motivating data set for the method development that lead to the cpr package. The DHS data cannot be made public, so this simulated data set has been provided for use in examples and instructions for use of the cpr package.
